The Von Däniken Storyline Was Entertaining, But Not Very Illuminating

The Swiss writer Erich von Däniken recently died at the age of 90 from natural causes. Many millions bought his books promoting a theory that Earth had been visited by astronauts in the past. Very prone to try to diminish contrarians outside of its intellectual "ruling class," the New York Times has an obituary on von Däniken with a subtitle claiming that his 1968 book "Chariots of the Gods?" sold "hundreds of thousands" of copies. But a Yahoo article tells us that von Däniken's books sold 70 million copies. And a 1970's version of "Chariots of the Gods?" claims that there are 4,000,000 copies of it in print. 

The approach taken by von Däniken in his first best-selling book "Chariots of the Gods?" was not anything obviously unreasonable. Again and again he would discuss very impressive examples of ancient engineering or ancient architecture or ancient inventions. He would suggest that such works of engineering or architecture or invention were beyond the very limited capabilities of the humans living at the time, and he would suggest that this may be evidence that humans received assistance from extraterrestrial visitors. He would also draw attention to ancient artwork or ancient literary passages that could be interpreted as suggesting visitors from the sky.

There were many subsequent books by von Däniken and others that expounded on these ideas. Mainstream authorities noticed all the book sales of  von Däniken, and expressed hostility. Much of that hostility can be explained as jealousy. I remember in the 1970's watching mainstream astronomer Carl Sagan on the Tonight Show denouncing  von Däniken and his claims. There were two reasons for  not trusting Sagan's criticisms. The first is that von Däniken's books dealt mainly with archaeology, and Sagan was no scholar of archaeology. The second reason was that Sagan himself had advanced speculations similar to those in von Däniken's books, a few years before the publication of  von Däniken's Chariots of the Gods? book. In the pages preceding and following these two pages in his 1966 book Intelligent Life in the Universe, Sagan spent quite a bit of time speculating in the style of von Däniken. Maybe Sagan was jealous that von Däniken had made millions from a speculation that Sagan had earlier advanced, while Sagan had not profited from the idea. 

A huge boon for the ideas of  von Däniken occurred around 2009 with the premier of the Ancient Aliens TV show, which ran for many years. The show introduced many millions to his ideas, and he was frequently seen on the show promoting his theories. The theory that extraterrestrial visitations helped produce various ancient wonders was a good fit for a TV series. We got very many travelogue-type shows in which some series host would appear at some exotic world location, and speculate about how extraterrestrial visitors might have helped produce the ancient wonders at the visited site. This made watchable TV footage. 

In his 1968 book "Chariot of the Gods?" von Däniken never mentioned DNA or genes. But an idea involving genes became a key part of the Ancient Aliens TV series. For more than a dozen years the show pushed the same central explanation for human beings, one that does not work well to explain who we are and how we got here.  The core explanation offered by the show was that at one or more points in the past, extraterrestrials altered human DNA. 

We had a presentation of this core explanation at the 38:55 mark in the  "Alien Operations" episode of Season 6, which you can see on Netflix. At the 38:55 mark we had this presentation:

 Klemens Hertel, molecular genetics phD: "What we don't know about humans in terms of evolutionary genetics is based on what we don't know about genetics nowadays. For example, we do not know the genetic basis of the thought process.  We don't know memory. We cannot create any ideas of how changes occurred to evolve the human brain to the functional being that it is right now."

Narrator: Could this incredible map [of the human genome] eventually solve the great mystery of human evolution? Might it help explain why humans, unlike any other living species, can think, reason and have the power of speech, or why they can create art, music, and spend time contemplating the reason for their own existence?

Graham Hancock: "It's not until about 40,000 years ago that you get a very radical change in human behavior.  Our hunting strategies get better.  Our tools and our weapons get better. It's as though some untapped faculty of the human brain and of the human imagination switched on."

Narrator: "Is it possible that the reason humans suddenly evolved from primitive beasts to sentient humans is due to otherworldly intervention? According to ancient astronaut theorists, the answer is a profound yes." 

Gorgio A. Tsoukalos: "One of the basic tenets of the ancient astronaut theory suggests that a long time ago, our DNA was artificially changed by extraterrestrials. And we can see that this is exactly what happened,  because all of a sudden we made a giant intellectual leap, and all of a sudden we became Home sapiens sapiens. "

David Childress"This was the time when the very first extraterrestrial genetic engineering took place. And in some ways, this was like phase one in the creation of modern humans beings as we know them."

Narrator: "Did extraterrestrials deliberately alter Homo sapiens DNA?"

The books of von Däniken contain similar speculations about DNA and genes. On this page and the next page of his 1976 book "Miracles of the Gods," von Däniken erroneously refers to DNA as containing "all the hereditary information and cell building plans of living creatures," a claim that is inaccurate because DNA does not have any plan or specification of how to build any cell or any of its organelles.  On page 218 of the same book,  von Däniken dogmatically states the shakiest of speculations, telling us, "Homo sapiens became intelligent only after the visit by extraterrestrial beings." On the same page he refers to "the extraterrestrial beings who made us intelligent by artificial mutations," referring most speculatively to gene tinkering of humans by visitors from some other planet. 

On the page here of the same book, von Däniken speaks as if he fully believes in "brains make minds" dogma.  On the page here of the same book, he says "when they 'grafted' their own genetic characteristics onto hominids," using "they" to refer to extraterrestrials, and hominids to refer to humans or human ancestors. Strangely, in the same sentence he claims that extraterrestrials transferred ESP powers from themselves to humans, by genetic manipulation. The speculation sounds like folly, because the well-established reality of telepathy and ESP has no neural or genetic or bodily explanation (which is part of the reason why materialists refuse to accept the strong evidence for ESP). 

You can summarize the typical explanations of today's Darwin-venerating biologist like this: "Evolution explains DNA; DNA explains bodies; bodies explain minds."  Every part of that explanation is wrong. Evolution in the form of unguided Darwinian natural selection does not offer a credible explanation of what we see in human DNA: about 20,000 types of genes that correspond  to more than 20,000 human protein molecules.  Each a repository of fine-tuned information representing a functional sequence of hundreds or thousands of well-arranged amino acid parts, such genes are too hard-to-achieve through an accumulation of random mutations as imagined by Darwinists. DNA does not explain human bodies.  Contrary to the myth so often told by biologists and chemists, DNA is not any specification for how to build a human body or even any of its organs or cell types. DNA does not even specify how to make the main components of cells: organelles and protein complexes. All that DNA specifies is very low-level chemical information such as which amino acids make up particular proteins. Very many scientists have confessed this reality, and at the post here you can read a list of more than 30 scientists and doctors who tell us that DNA is not a specification, blueprint or program for making a human.  

As for the claim that bodies make minds, it is false. There are very many reasons (discussed in the posts of the blog here) why the human brain fails to be an explanation for the human mind and human memory. Ironically, the molecular geneticist quoted above on the Ancient Aliens show actually pointed us a bit in the right direction by saying this:

"For example, we do not know the genetic basis of the thought process.  We don't know memory. We cannot create any ideas of how changes occurred to evolve the human brain to the functional being that it is right now."

Yes, and neuroscientists do not have any substantive idea of how a brain could cause someone to think or remember.  A very thorough study of the many physical shortfalls of the brain will lead to the idea that the brain cannot be the cause of human mental phenomena such as very fast thinking and instant recall and the lifetime preservation of memories. 

What does the Ancient Alien series (and von Däniken in the 1976 book Miracles of the Gods) offer as a correction to the bungled explanations of typical biologists? You could explain it like this:

Bad old thinking: "Evolution explains DNA; DNA explains bodies; bodies explain minds."

Bad new thinking, "Ancient Aliens"/von Däniken  style: "Evolution and gene-tinkering by extraterrestrial visitors explains DNA; DNA explains bodies; bodies explain minds."

What the Ancient Aliens series gives us is just a rather timid tweak on the old nonsensical explanations of 1960's biologists. So instead of the idea that we got the wonders of DNA by only blind unguided processes, we now have the idea that some of human DNA is the result of purposeful interventions by visiting extraterrestrials. That might be a move in the right direction towards a more credible theory of how we got human DNA.  But a huge problem is the show's continual speaking as if some suitable DNA explains how we got humans.  You cannot explain humans by the arising of suitable DNA. DNA does not explain the origin of the human body. And neither DNA nor human bodies explain the origin of the human mind. 

DNA is no body blueprint

DNA does not explain the origin of any human body because DNA merely specifies very low-level chemical information such as which amino acids constitute a protein.  So we are left with the gigantic unanswered question: how is it that a speck-sized zygote in a newly impregnated woman is able to progress over nine months to become the vastly more organized state of hierarchical dynamical organization that is a full-sized human being? There is nothing in DNA and its genes and nothing known to biology that explains this progression, which is a miracle of organization a million times more impressive than a hotel-sized sandcastle with 100 ramparts and 20 turrets arising only from the wind and water at the edge of a beach. There is no hypothesis about extraterrestrials visiting long ago that can do anything to explain this ongoing marvel of hierarchical organization that is at the center of biology. 

Neither DNA nor anything in the brain explains the wonders of human memory and the wonders of the human mind.  DNA does not explain the arising of any human body, any human organ or any type of human cell, none of which is specified in DNA. So it does not work to claim that we got the marvels of our minds and memories because visiting extraterrestrials did something to alter our DNA. There is nothing in either our DNA or our brains that explains the main wonders of our minds. 

To explain the wonders of the human body and the wonders of the human mind, we need ideas far bolder than the rather timid idea that visiting extraterrestrials tinkered with human DNA. It is very strange that we seem to never get from the Ancient Aliens series the kind of reasoning that would best support its main explanatory claim. Such reasoning would require educating TV viewers about the stratospheric levels of fine-tuning and functional complexity of genes and protein molecules, and the mountainous heights of dynamic hierarchical organization in the human body. TV viewers would get an explanation of why the average gene is something as unlikely to arise by unguided processes as a well-written useful grammatical paragraph of 100 or 200 words arising from an ink splash. TV viewers would get an explanation of why you cannot credibly explain the origin of such repositories of functional information by imagining an accumulation of random mutations. TV viewers would be educated in the relevant probability mathematics, and fundamental principles such as that the chance of the accidental origin of a functional structure skyrockets in a geometric and exponential fashion whenever there is a simple linear increase in the number of well-arranged parts needed for such a structure. After such an education, the viewers could be told that it is just too improbable that unguided Darwinian evolution could have produced such wonders of functional complexity, and that we must postulate some guided assistance, which could have occurred by extraterrestrial intervention. 

But such a presentation seems to never occur on the Ancient Aliens show. Instead the show seems to spend the vast majority of its time trying to persuade us that various wonderful-seeming things (in history or in legend) are things suggesting extraterrestrial visitors in the past. The results rarely sound convincing, although the show does serve as an entertaining vehicle for educating us about facts and aspects of human history and bygone human culture. 

Erich von Däniken had a very erroneous conception of the nature of DNA and its genes, and a very erroneous conception of the nature of brains and memory.  For example, on page 48 of his book Gods from Outer Space, he falsely stated, "Today it is an accepted scientific fact that memories are stored in memory molecules and that RNA and DNA molecules transport memory molecules." No such thing was ever established by scientists. On page 23 of the same book he falsely stated, "DNA contains genetic information for building the cells, as well as all the other hereditary factors." On page 24 he just as falsely stated, "DNA is the perfect punched card for the structure of all life." On page 49 he falsely stated, "We know that the nucleus of the gene contains all the information needed for the construction of the organism." 

Containing only low-level chemical information, DNA and its genes do not specify the structure of bodies, organs or cells, and do not have instructions for how to build such things (as I discussed in 2016 and in many other posts on this blog). We cannot blame von Däniken for these misstatements, because we was simply parroting misstatements that were being made by many scientists at the time he wrote. It is ironic that von Däniken was condemned by scientists such as Carl Sagan, when it was a situation where von Däniken was building a "castle in the clouds" of speculation largely based on DNA myths that scientists such as Sagan had been guilty of promoting

For very much more on why the bad old thinking discussed above really is bad thinking, see my long post "Evolution Does Not Explain DNA, DNA Does Not Explain Bodies, and Bodies Do Not Explain Minds."

We should give some credit to von Däniken, despite his overconfident dogmatism and many errors. He was a very diligent person whose books sold in gigantic numbers, and you have to be doing some things right for that to happen. We can credit von Däniken with being smart enough to recognize that the standard account of human origins was not credible. But unfortunately von Däniken's scholarship of biology, brains, minds and human mental experiences was much weaker than his scholarship of archaeology. Having started out in the late 1960's with a weak theory attempting to fix the gigantic shortfall of scientific explanations of human origins, he stuck with that theory all of his life, never realizing that to bridge that ocean-sized shortfall you need a reality gigantically greater than just some extraterrestrial spaceships visiting long ago.

The Explanatory Timidity at the Core of the "Ancient Aliens" Series

The History Channel's Ancient Aliens TV series is now in its nineteenth season. Some may think that the show has been very bold from an explanatory standpoint, willing to stick its neck out by engaging in outlandish-sounding speculation. We do see on the show a discussion of history and folklore that boldly attempts to suggest extraterrestrial intervention throughout human history. An example was an episode that discussed the British legend of Merlin, the teacher of King Arthur, reputed to have magic powers. The show suggested that maybe Merlin's suite of magic powers was some extraterrestrial technology Merlin was using.  A similar type of suggestion has occurred a hundred times on the "Ancient Aliens" show, such as a show trying to suggest that the Ark of the Covenant was some machinery built by extraterrestrials, and a show suggesting the Vikings had extraterrestrial help in forging metal, and that Valhalla was an extraterrestrial spaceship.  A standard formula of the show is to discuss some ancient or medieval marvel or legend, and to try to suggest that it arose because of some kind of mysterious interaction humans had with extraterrestrials.  For example, at the 39:35 mark of the Season 5 Ancient Aliens episode "The Monoliths," we hear David Childress saying this:

"And then we have these ancient obelisks that were at one point apparently, all around the world.  It would seem that there was a worldwide system similar to a wireless broadcasting system. These obelisks would broadcast power into the atmosphere,  and remote locations around the world could pick up that power, much like a radio today, or a television set, or a satellite phone, or a computer. This seems to be the system that was set up by extraterrestrials thousands of years ago on this planet, and incredibly, they didn't just do it on planet Earth."  


The episodes that use this formula may have a certain amount of speculative boldness. But the core explanation offered by the "Ancient Aliens" show is actually an example of explanatory timidity. I have been watching this show for many years, and I have noticed no real progression in its core explanation.  For more than a dozen years the show has been pushing the same central explanation for human beings, one that does not work to explain who we are and how we got here.  The core explanation offered by the show is that at one or more points in the past, extraterrestrials altered human DNA. 

We had a presentation of this core explanation at the 38:55 mark in the  "Alien Operations" episode of Season 6, which you can see on Netflix. At the 38:55 mark we had this presentation:

 Klemens Hertel, molecular genetics phD: "What we don't know about humans in terms of evolutionary genetics is based on what we don't know about genetics nowadays.

The results rarely sound convincing, although the show does serve as an entertaining vehicle for educating us about facts and aspects of human history and bygone human culture. 

You may realize there's a kind of explanatory timidity of the Ancient Aliens series when you consider that the main idea advanced by the show is the idea that extraterrestrials engaged in gene splicing long ago; and gene splicing is a technology that humans already possess.  Knowing that intelligence could have arisen on other planets any time in the past billion years, and could easily be many millions of years older than mankind, astronomers have assumed that any extraterrestrial civilization reaching our planet would have god-like powers dwarfing our own. But you're not imagining any god-like power if you imagine visiting extraterrestrials doing some fiddling with human DNA. Humans already know how to fiddle with DNA. 

Part of the problem is the show's title. The show should have had some title that did not chain it to one particular explanation. With a title such as "Human Origins: Contrarian Ideas" the series would have been free to move beyond its "von Daniken straightjacket." But with the title "Ancient Aliens" the TV series is chained to the same old explanation, year after year.  It's rather like how the typical biology professor stays chained to the same old bad explanations decade after decade, parroting a "same old same-old" origins storyline reminding us of the 19-year run of the Ancient Aliens series. Just as the Ancient Aliens series clings religiously to the same old conventions year after year (such as lamely trying to validate speculations by claiming that "ancient astronaut theorists" believe them, and by pronouncing the word "extraterrestrial" in a way emphasizing the "res" syllable), our biologists cling to the same old dubious conventions year after year, such as promulgating the legend that vast wonders of biological organization not yet discovered in the 19th century were explained by someone who died in that century (which is kind of like claiming that smartphones or tablet computers are explained by something in the writings of Plato). 

Imagining gene-splicing ancient extraterrestrial visitors does not really help in origins problems.  Each a very complex functional invention requiring hundreds or thousands of well-arranged parts, the fine-tuned genes and protein molecules in the human body are so mathematically improbable to arise by unguided processes that we should expect none of them to arise by unguided processes in the history of the observable universe, even if there are a billion trillion planets in such a universe.  You don't help that problem by imagining that such miracles of luck occurred on a nearby solar system, helping to give rise to extraterrestrials who came to Earth to tinker with human genes.  That's kind of like "robbing Peter to pay Paul," just moving the "unbelievable 20,000 miracles of luck" from one solar system to another one.  It's kind of like someone answering the objection "a house of 52 well-arranged cards could never arise by someone throwing a deck of cards into the air with his left hand" by saying "I didn't use my left hand to throw the deck of cards into the air; I threw the deck of cards with my right hand."  

For the truth about the bad old thinking discussed above, see my long post "Evolution Does Not Explain DNA, DNA Does Not Explain Bodies, and Bodies Do Not Explain Minds."

"Ancient Aliens" Mixes Marvels, Mysteries and Misconceptions

The long-running TV series "Ancient Aliens" has long been a strange mixture of the daring, the dazzling and the dubious. On the positive side, the show often draws our attention to interesting anomalies worthy of our attention, anomalies that have too often been wrongly swept under the rug by mainstream scientists.  Also on the positive side, "Ancient Aliens" often raises objections to doubtful dogmas of academia that should indeed be questioned. On the negative side, "Ancient Aliens" often pushes its owns doubtful dogmas, along with speculations that are not very credible.

The show sometimes suggests ETs had something to do with Stonehenge

Such strengths and weaknesses were shown in a recent episode of "Ancient Aliens" entitled "The Human Experiment," one that was a weird smorgasbord of interesting journalism, unbelievable speculations, weighty considerations well-worth pondering, and untrue claims. The episode was mainly devoted to advancing an  unbelievable claim constantly repeated on the show: that humans became humans because extraterrestrials tinkered with our DNA. 

The reason why this claim is unbelievable is not because of some impossibility that extraterrestrials visited us in the past. The two main reasons why this claim is unbelievable are these:

(1) There are no conceivable modifications in DNA that can explain the physical origin of human bodies, because DNA does not specify anatomy, contrary to the mythical claims to the contrary that have often been made by scientists and science writers. DNA uses a system called the genetic code in which chemicals in DNA (called nucleotide base pairs) stand for amino acids that make up proteins. But under such a system there is only a very limited capacity for specification. DNA (and the genes that make up DNA) can only specify low-level chemical information such as  the amino acids that make up proteins, and the contents of RNA molecules. When scientists discovered the genetic code used by DNA, they only discovered an extremely limited coding scheme completely incapable of specifying complex three-dimensional structures such as the layout of a human body or the structure of an eye or the layout of the human reproductive system or even the structure of any cell.  Read the posts here, here and here for more on why DNA cannot be a specification of anatomy. In the post here you will read quotations from more than twenty biologists, chemists and doctors who say that DNA is not a blueprint or a recipe or a program or an algorithm for building a human body. 

(2) Things such as the origin of language and the origin of the human mind cannot possibly be explained by extraterrestrials tinkering with human DNA.  Because DNA does not specify anatomy, DNA changes cannot explain the physical structure of the brain. Also, the brain does not explain the human mind or the capabilities of human memory, for reasons abundantly explained in the posts of the site here.  In short, DNA does not explain brains, and brains don't explain minds. So the idea that humans got their advanced minds and language by extraterrestrials modifying our DNA is unbelievable. 

I would describe the "ancient astronaut theorists" constantly evoked on the "Ancient Aliens" program as being half-rebels or quarter-rebels. On one hand, such theorists are willing to rebel against the silly origins dogmas of academia, by pointing out that human minds and human culture appeared on the scene too quickly to be explained by any ideas of mainstream professors.  On the other hand, such ancient astronaut theorists seem to accept "hook, line and sinker" some of the least believable ideas of mainstream professors. Our ancient astronaut theorists seem to uncritically accept incorrect ideas that DNA is some "explain-it-all" molecule that can explain human minds and anatomy. It is no such thing, but merely a piece in the grand puzzle of human origins.  Such ancient astronaut theorists also seem to accept "hook, line and sinker" unwarranted claims that human minds can be explained by brains. 

In the recent "Ancient Aliens" episode on DNA, we had several misstatements about DNA.  The narrator claimed that DNA is a molecule that defines every creature on Earth. DNA is no such thing, but merely a very important chemical database used by living things.  The structure of cells is not specified by DNA, nor is the anatomy of organisms.  We had a statement by biologist Kirsten Fisher, making this give-us-the-wrong-idea  claim: "The DNA code is essentially like a language consisting of genes that confer particular traits like eye color, hair color, all these traits basically that we recognize." DNA is only a code by which nucleotides stand for amino acids, and is not "essentially like a language," because it has nothing but the tiniest vocabulary  consisting only of about 25 nouns (each an amino acid), no verbs except "stop," no adjectives, and no grammar. 

DNA has no power to specify things three-dimensional arrangements of parts the way languages do.  While DNA may be important in determining eye color and hair color, it is very false indeed to claim that it confers "all the traits basically that we recognize." DNA does not specify human anatomy or even the anatomy of cells, nor does it specify human intellectual traits such as the ability to think, consciousness, morality, the ability to form memories, the ability to recall memories,  and so forth.  For example, the traits that we have ten fingers and ten toes and two eyes and one nose and one mouth are not specified by DNA. So it is very false to claim that DNA confers "all these traits basically that we recognize." The genome is not a blueprint," says Kevin Mitchell, a geneticist and neuroscientist at Trinity College Dublin, noting "it doesn't encode some specific outcome.""DNA cannot be seen as the 'blueprint' for life," says Antony Jose, associate professor of cell biology and molecular genetics at the University of Maryland, who says, "It is at best an overlapping and potentially scrambled list of ingredients that is used differently by different cells at different times."  

We should have suspected that we were being given the wrong idea by biologist Fisher by the fact that she only gave the specific  examples of eye color and hair color as traits conferred by DNA.  When she said, "The DNA code is essentially like a language consisting of genes that confer particular traits like eye color, hair color, all these traits basically that we recognize," it sounded like some male suitor saying, "I'm so rich: I have a pencil and a small jar of coffee and every other thing a man could possibly dream of having."

We then hear another scientist (Adam Siepel) making the  also untrue statement that "in a sense DNA is a program that gets run by the computer, and the computer is a cell." No, DNA is not a program, and it lacks the essential characteristic of a computer program, which are conditional logic statements such as "if/then" statements.  The correct computer analogy for DNA is to compare to not to a program but to a primitive database -- not a modern relational database which can include logic in the form of stored procedures, but merely the simplest databases that merely have data.  Although cells are vastly more complex than molecules (way too complex to be explained by anything in DNA), cells are not computers that run programs. 

Beware of biologists using phrases such as "essentially like," "basically" and "in a sense." Alarms bells should go off in our minds when we hear such words, and we should be suspicious that at best someone is saying something that is not literally true, and that at worst someone is starting to shovel baloney. 

In the "Ancient Aliens" episode I am discussing someone claims that DNA is "essentially digital." That is untrue.  Information either is digital or is not digital, and calling something "essentially digital" is like saying someone is "essentially pregnant." When information is digital, it consists of sequences equivalent to ones and zeros, sequences such as 1010101001111100010101.  None of the information in DNA is digital. 

The "Ancient Aliens" episode unconvincingly tries to cite human genetic engineering with CRISPR as something that helps supports claims that aliens tampered with human DNA. It is suggested that "DNA knots" are evidence of extraterrestrial tampering. We have a rather ridiculous attempt to persuade us that some short slightly winding symbol found in ancient Egyptian art is a depiction of the double helix, something we are told "cannot be by chance." Someone describes the DNA double helix co-discoverer Francis Crick as someone who promoted the idea that extraterrestrial visitors were the origin of "human DNA." But in his paper on the topic, Crick merely spoke vaguely of extraterrestrials being the origin of "terrestrial organisms," and said "the scientific evidence is inadequate at the present time to say anything about the probability."

We hear the very strange suggestion that humans are smarter than chimps because we have two fewer chromosomes than chimps. After a long attempt to convince us that humans arose because extraterrestrials modified our DNA, the episode went into a discussion of other topics. There was a discussion of people claiming that they were abducted by extraterrestrials,  people such as Betty Hill and Barney Hill. We hear an interesting account from a woman who claimed that her pregnancy ended when extraterrestrials extracted the growing 4-month-old child from her womb. 

The "Ancient Aliens" episode then has some noteworthy footage of blindfolded children apparently demonstrating powers of clairvoyance.  The demonstration seems persuasive, because the large completely opaque blindfolds are very solid material maybe twice as large as large sunglasses, extending way below the eyes; and the children are looking straight ahead at targets two meters away at eye level, without tilting their heads backwards (ruling out the "looked through the bottom crack of the blindfold" objection made by skeptics).  The footage is from the film "Superhuman: The Invisible Made Visible" by Caroline Cory.  

I strongly suspect that neither cheating nor faking is going on here, because of the factors mentioned above and because similar clairvoyance results by children have been very well documented in the Soviet Union and China, as discussed in my post here, entitled "EHF: Reports of Chinese Kids With Paranormal Powers."  I asked only one person from China whether she had ever heard of such reports, without any reason to think that she had. She said that she had a relative who had demonstrated such powers as a child  (including the power to see inside a closed box), and that this relative was brought to Beijing to be tested by the government.  

The fact is that we have nearly two hundred years of well-documented evidence for human clairvoyance, from all over the globe, provided by a host of reliable witnesses. The evidence stretches back all the way to the report of the French Royal Academy of Medicine issued in 1831, one finding in favor of clairvoyance. Clairvoyance has been well-documented by esteemed authorities such as Professor William Gregory, a chemistry professor at the very prestigious University of Edinburgh who documented at very great length his observations of clairvoyant subjects.  The written nineteenth century evidence and early twentieth century evidence for clairvoyance during states of hypnotism and trance is extremely abundant, and clairvoyance was well-demonstrated in a host of public exhibitions and experiments.  The fact that so many contemporary professors deny the existence of clairvoyance is one of the most outrageous modern examples of denying solid evidence, typically made by people who never studied the original source evidence (such as the cases discussed here). 

The fact that the "Ancient Aliens" episode on DNA has presented some modern evidence for clairvoyance is commendable. But in the same episode we are shown the filmmaker Caroline Cory who has filmed this evidence, participating in a panel discussion with ancient astronaut theorists. Perhaps to fit in with all of their talk about extraterrestrials tinkering with human DNA, Caroline suggests that extraterrestrials might have upgraded our DNA to give humans the power of clairvoyance.  Caroline not only suggests this idea, but says "I guarantee you" that extraterrestrials are modifying our DNA. 

This explanation makes no sense at all.  Clairvoyance and other psychic phenomena such as telepathy and near-death experiences can never be explained by anything in DNA, nor can they be explained by anything in human brains. Such phenomena can only be explained by ideas such as the hypothesis that humans have souls, or some spiritual capability that is the equivalent of having souls.  This is very probably why materialists have for so long stubbornly refused to accept almost two hundred years of very convincing evidence for clairvoyance: because they know that once you admit the existence of clairvoyance, the existence of something like a human soul is all but certain. 

There is no evidence that people who score higher on ESP tests or clairvoyance tests have different DNA than average people. There is no evidence that anyone has DNA much different from average people, with the exception of people with birth defects.  Contrary to clickbait headlines exaggerating small changes, human DNA has changed very little over the past two thousand years, with the main changes being mainly related to not-very-important things such as eye color, hair color and lactose digestion. So genome analysis does not support a claim that extraterrestrials are modifying our DNA.  

It's rather a shame that the "Ancient Aliens" show originally chose the title of "Ancient Aliens." That title is kind of a ball-and-chain that its writers are tied to, a kind of prison that limits them. It would have been better if the show had a more noncommittal title, something like perhaps "Mysterious Beginnings" or "Contrarian Theories." That way, the show could have progressed beyond its Erich von Daniken beginnings. But with the title "Ancient Aliens" the show is kind of chained to an original hypothesis, not very free to move out to more credible theorizing. Conversely, I am glad that I chose for this blog the noncommittal title of "Future and Cosmos," along with a subtitle ending with the phrase "...and other weighty topics." With such a title and subtitle I have felt free to move in whatever direction I felt was most consistent with what I have learned during years of study on a very wide variety of topics, without having to feel that I have to stay consistent with some box-me-in title. If you ever start a new blog detailing your thoughts on philosophy, politics, science or religion, I advise picking some blog title that does not box-you-in to some position you may later move away from. 

Postscript: On the Travel Channel's UFO Witness show, we have an account by one of the people claiming an alien abduction experience. We are told the account arose after "hypnotherapy." But accounts told under hypnosis are suspect, because under hypnosis subjects can be extremely suggestible. This was reported by Professor William Gregory as far back as the nineteenth century, on the page here, where he indicates that hypnotized people can be made to believe almost anything suggested.  To judge the reliability of the "abduction account," we would need to read a transcript of what the hypnotist and patient said.  Did the account of extraterrestrials arise after such an idea was suggested by the hypnotist? Or did it arise when the hypnotist acted neutrally, asking something like "Tell me about what happened on the night when you were puzzled by what happened"?

How Well Do ET Visit Theories Plug the Holes in Mainstream Scientist Explanations?

To casual students, the explanations of mainstream scientists may seem like mighty edifices. But a closeup inspection of the pillars holding up such edifices may leave you shaking your head in doubt. 

pillars of Darwinism

There are many grave shortfalls in the explanations of mainstream scientists, which are far more serious than our overconfident authorities admit. To help plug some of these gaps, some appeal to the idea that Earth received extraterrestrial visitors in the past, and possibly also the present. The most influential exponent of this view is probably the long-running television series
Ancient Aliens. How well do theories of visiting spaceships plug the giant holes in the explanations of mainstream science? Let's look at some specific problems, and consider to what degree they can be alleviated by evoking the possibility that extraterrestrial spaceships visited Earth in the past or present.

Problem #1: The Problem of the Origin of Life

Mainstream science has failed to offer a credible explanation for the origin of earthly life. Even the simplest form of microscopic life is such a high level of organization that we would never expect it to appear by chance from chemical processes even once in the history of the universe.  The concept of abiogenesis (the chance appearance of life from mere chemicals) is a concept which has not been supported by any experiments realistically simulating the early Earth. We merely have a long history of scientists making unfounded statements insinuating progress on this topic. 

To some it might seem that the problem of explaining the origin of earthly life is one that we can greatly alleviate by assuming extraterrestrial visitors. As the universe is about 13 billion years old, it is conceivable that life might have arisen on some other planet as early as 8 billion years ago, that intelligent life may have arisen as early as 4 billion years ago, and that intelligent visitors from other planets may have come to our planet as early as 3 or 4 billion years ago. So we can imagine some extraterrestrial visitors planting the first life that appeared on Earth.

Such a scenario may offer as much as a billion-fold reduction in the improbability of earthly life naturally appearing. Let us suppose that the probability of life originating on any planet orbiting in a star's habitable zone is 1 in X, where X is some very large number. If we suppose that such an event could have been caused by extraterrestrial visitors coming from any of a billion planets in our galaxy, which has perhaps as many as a billion planets in the habitable zones of sun-like stars, then it might be that the probability of earthly life appearing may have been as high as 1 in X times 1,000,000,000. A multiplier of more than 1,000,000,000 should not be used, because we should be excluding visitors from other galaxies, which are too far away to be credible spots where visitors to Earth may have originated.

Such a billion-fold improbability reduction may seem like a very big deal. But if you make a really realistic estimate of the probability of life accidentally originating from chemicals, it would seem that such a billion-fold improbability reduction is not very significant. The problem is that a realistic estimate of the probability of a chance appearance of life from non-life will give you a probability such as 1 in 10 to the thousandth power.  If you increase such a probability by a billion fold, you still are left with a probability that is something like 1 in 10 to the thousandth power. So while imagining visiting extraterrestrials could help explain the appearance of life on our planet, imagining such a thing does not help explain how life could have ever appeared in our galaxy.  With or without visiting extraterrestrials, we have no credible theory of the natural origin of life in our galaxy. 

Problem #2: The Problem of the Origin of Visible Earthly Organisms

Mainstream science fails to credibly explain the origin of visible earthly organisms, contrary to the unwarranted boasts on this topic made by current and past biology professors. One reason for this failure (not by any means the only reason) is that mainstream science fails to offer a credible explanation for the origin of the protein molecules used by visible earthly organisms. Such protein molecules are fine-tuned arrangements of hundreds of amino acid parts. In the natural world there are billions of different types of protein molecules, each one a different complex invention.  We would never expect any new type of protein molecule to appear by chance, such a thing being as unlikely as sea shells on a beach accidentally spelling out a useful message of hundreds of words.  Confessing how current theory fails to explain protein molecules, a science paper says, "A wide variety of protein structures exist in nature, however the evolutionary origins of this panoply of proteins remain unknown." 

It might seem that we can plug this explanatory hole by imagining extraterrestrial visitors in the past. We can imagine such visitors doing genetic tinkering or genetic engineering that might have originated countless different proteins partially specified in the genomes of many different organisms. But what about the problem that apparently these proteins originated not at one time, or in one geological era, but in multiple geological eras? We can get around that by simply imagining multiple extraterrestrial visits occurring during many different eras. Extraterrestrial spaceships could have come to our planet thousands of times in the past, and in many of these visits, there might have been tinkering with the DNA of earthly organisms 

But unfortunately, this does not solve the problem of explaining the origin of visible earthly organisms. The problem is that you can never explain the origin of a dramatically new earthly life forms by simply imagining some change in DNA.  This is because contrary to the misstatements that are so are often told on this topic, DNA does not specify anatomy. DNA does not specify how to make bodies, organs, skeletal systems or even cells. DNA merely specifies low-level chemical information.  You can read many scientific authorities confessing such a reality in the quotes I list in this post. 

So how did Earth get so many types of large organisms? We can't explain that through Darwinian explanations, since such explanations are limited to changes in DNA.  It seems we also cannot explain the origin of large earthly organisms by imagining purposeful additions or rearrangements of DNA by visiting extraterrestrials.  There are no changes in DNA that can explain the appearance of large new types of life. 

Problem #3: The Problem of Explaining Ordinary Human Minds

One of the biggest shortfalls of mainstream science is its utter failure to credibly account for the ordinary capabilities of human minds.  Scientists try to explain all human mental activity as simply being caused by brains. But neurons and synapses have properties which make them unsuitable as an explanation for human mental activity. 

Neurons and synapses are:

Very slowSynaptic delays, synaptic fatigue and the slower transmission speed of dendrites should prevent brain signals in the cortex from traveling at much more than a snail's pace of about a centimeter per second (conversely, humans can recall very obscure rarely remembered facts instantly). 
Very volatile and unstableSynapses and dendritic spines are made of proteins with lifetimes of only a few weeks or less, and individual synapses and individual dendritic spines don't last for years, unlike memories lasting decades.
Very noisyThere are many types of noise in neurons and synapses which should strongly inhibit reliable signal transmission.
Not addressableThere is no position location system in the brain by which some exact neural location could be looked up by using its address, to achieve fast recall.
Signal-suppressiveA synapse in the cortex will transmit a signal with a likelihood of between .1 and .5, which means brain signals are constantly being suppressed.
DisorganizedNeurons are like the spaghetti mess in a huge cafeteria pot, and are not highly grouped into organizational units like letters in a book or computer components.
IndistinctNo one has discovered any distinctive marks or signs of encoded information in neurons or synapses other than the DNA information about the same in every cell.
Neither readable nor writableNo one has been able to specify how episodic memory information could be written to or read from neurons or synapses.
Largely dispensableThere are many medical cases of people suffering little damage to their minds or memory even though they lost very much of their brains, as much as 50% or 75% or more. 


Given such characteristics of neurons and synapses, there is no credibility in attempts to explain human mental activity as being caused by brains.  Does the hypothesis of extraterrestrial visitations help with this explanatory problem? Not at all.  On the Ancient Aliens show, the speakers are constantly hypothesizing that extraterrestrials tinkered with human DNA.  But since there is nothing in either the human DNA or the human brain that can explain the main impressive features of ordinary human mentality, such a hypothesis does nothing to help with this explanatory problem. 

Problem #4: The Problem of Explaining Paranormal Psychic Phenomena

There is a wealth of evidence for paranormal psychic phenomena. For example, a significant percentage of the population reports having near-death experiences, and very many of them report out-of-body experiences. To give another example, very many humans have reported apparition sightings, often reporting an apparition of someone appearing at the time that person died, before the person's death was known to the person seeing the apparition. Does the hypothesis of extraterrestrial visitations help explain such things? No, it does not.

Problem #5: The Problem of Morphogenesis

A great problem that mainstream science miserably fails to explain is the problem of morphogenesis. We may define this as the problem of explaining how it is that a fertilized egg is able to progress to become a full-grown organism. For many years important figures in mainstream science have suggested a solution to this problem that is utterly false: the baloney explanation that such a progression occurs because there is a reading of a blueprint or recipe for making an organism, stored in the DNA of the organism. No such blueprint or recipe exists in DNA. DNA merely specifies low-level chemical information, not high-level biological structural information. 

The claim that full-grown organisms arise because a DNA blueprint is read is a claim that is both false and very childish, like a very small child's claim that astronauts first got to the moon by riding a big balloon.  Just as a balloon built to reach the moon would never get there (not rising after it left the atmosphere), if there existed in DNA a blueprint for building humans it would not give rise to organisms, because blueprints don't cause things to be built. Construction only occurs by means of a blueprint because there is a construction crew that reads and understands the blueprint instructions, and carries them out. We know of nothing below the neck of a female that could read and understand and execute fantastically complicated instructions for building hierarchically-organized humans if such instructions happened to exist in DNA, which actually only contains low-level chemical information, not instructions for constructing anatomy.  

So how is it that a fertilized egg is able to progress to become a full-grown organism? We absolutely do not understand this great mystery. This is one of the supreme explanatory shortfalls of modern science. The mystery only deepens when we consider the fantastic degree of hierarchical organization in full-sized organisms.  

Subatomic particles are organized into atoms, which are organized into relatively simple molecules such as amino acids, which are organized into complex molecules such as proteins, which are organized into more complex units such as protein complexes and cell structures called organelles, which are organized into cells, which are organized into tissues, which are organized into organs, which are organized into organ systems, which (along with skeletal systems) are organized into organisms.  The end result of a human body is something more organized and functionally complex than anything that humans have constructed with their hands. Humans know how to put together an aircraft carrier (fully equipped with 80 jet fighters)  piece by piece, but there is no team of scientists that could come anywhere close to putting together a full-sized living human body by some piece by piece assembly of molecules. 

mystery of reproduction

It is rather obvious that the theory of extraterrestrial visitations in the past cannot help us with this difficulty. The morphogenesis of organisms is something happening right now, all over the world. Unless you want to imagine extraterrestrials on almost every street in the world, it is hard to imagine any way in which extraterrestrials can help us with this problem of explaining the progression from a tiny speck-like ovum to a large full-grown organism.

Problem #6: The Problem of the Universe's Origin

A great problem that mainstream science miserably fails to explain is the problem of how the universe originated. It is believed that the universe suddenly appeared about 13 billion years ago, in the mysterious event called the Big Bang.  Because such an event is believed to have occurred billions of years before any planets formed and before any life existed, postulating extraterrestrials or extraterrestrial visitors is of no use in explaining the universe's origin.

Problem #7: The Problem of the Origin of Language

Mainstream science lacks any credible theory of the origin of language. You can read in this post about this shortfall.  Part of the problem is that it seems inconceivable that any language could get started in a community unless there was some teacher or teachers that already had a language. 

You could apparently plug this hole fairly well by imagining extraterrestrial visitors. We can imagine spaceships landing, and extraterrestrial visitors emerging, with such visitors teaching humans how to speak some language. 

Problem #8: The Problem of Our Lucky Solar System

Our solar system seems to be an exceptionally good place for hosting life and intelligent life.  You could hardly ask for a luckier arrangement than to have a planet like Earth with a moon such as it has, a moon that some people think helped play a role in aiding life's appearance.  The arrangement of planets in the solar system aids the habitability of Earth.  Very large planets like Jupiter and Saturn help to attract passing asteroids or comets (by means of the gravitational fields of such planets), making it relatively unlikely that Earth will get hit by such objects. A recent study suggests that solar systems with planets allowing photosynthesis may be very rare, another reason for thinking there's something special about our solar system.  Thousands of extrasolar planets have been detected, but the study says, "So far, we have not observed terrestrial planets comparable to Earth in terms of useful photon flux, exergy, and exergetic efficiency." .Another recent study says, "A modest axial tilt, like Earth's, helps increase the production of oxygen, which is vital for life as we know it - and planets with tilts that are too small or too large might not be able to produce enough oxygen for complex life to thrive."

Can we help explain such improbable luck by imagining visitors from other planets? Conceivably.  A civilization capable of traveling to other solar systems might have god-like powers over matter that might be sufficient for it rearrange the planets in a solar system, making some arrangement more suitable for the appearance and long-term survival of life.  Visitors from some other solar system might be capable of doing something such as turning a dry planet into a wet planet, by causing lots of icy comets to land on the dry planet. 

Problem #9: The Problem of Fine-Tuned Fundamental Constants 

Our universe has some fundamental constants that seem to have just the right values for allowing life to exist.  For example, the electric charge on each proton is the very precise opposite of the electric charge on each electron. This very exact match of the absolute values of the proton charge and the electron charge is a match that is necessary both for biochemistry and for stable planets.  There are quite a few other cases of fundamental constants with just the right values for the universe to be compatible with life. 

Can we imagine that extraterrestrials from other planets help produced this fine-tuning? No, we cannot.  No one has any idea of how any civilization could change any of the fundamental constants, no matter how great their technological power. That would seem to be as impossible as changing the value of pi so that instead of being 3.14 it was instead 7.84.  We also cannot imagine extraterrestrials arising in a universe that was not compatible with life, and such extraterrestrials then changing such a universe to be compatible with life; for if the universe had started out being incompatible with life, such extraterrestrials could never have existed.    

Conclusion

My answer to the question posed by this post's title is: "not very well."  A few of the holes in mainstream scientist explanations can be plugged or partially plugged by imagining extraterrestrial visitors. But most of the more gaping holes in mainstream scientist explanations cannot be plugged by imagining such visitors.  We need something a lot more than visiting spaceships to get us out of our biggest explanatory shortfalls.  

Last night I dreamed of a book with the title 100 Secrets of Eternity. In such a book might be the answers to some of the problems I have mentioned, answers never imagined by today's experts.
