Recent research has reported that the first life on Earth may have appeared between 3.8 and 4.3 billion years ago.[1] Though not mentioned directly in the news coverage, this finding is deeply unsettling for the scientific community, which has yet to establish a convincing scientific theory for the spontaneous emergence of life. Their hypotheses, which rely on astronomically low probabilities, lose persuasive power the shorter the time between Earth's formation and the emergence of life. Meanwhile, NASA captured widespread public attention with its announcement that seven Earth-like planets had been discovered just 39 light-years away.[2]
Professor Ignas Snellen, who participated in the peer review of the paper on these Earth-like planets, said this:
"One thing is certain: the small dwarf star TRAPPIST-1 burns hydrogen so slowly that its lifespan is expected to reach 10 trillion years… That is a long enough time for life to evolve."
— Ignas SnellenFor humans, who live at most around 100 years, 10 trillion years is certainly a long time. But whether 10 trillion years is long enough for life to spontaneously arise is an entirely different question. In this article, I want to discuss just how scientifically untenable the notion of spontaneous generation truly is — a claim that is often spoken of as though it were a matter of common sense.
01The Miller experiment and what it really means
In 1953, when our understanding of life was still quite limited, Stanley Miller filled a glass tube with methane, ammonia, hydrogen, and water vapour — the conditions then believed to represent early Earth's atmosphere — applied electrical shocks, and discovered that amino acids were produced inside. This finding led many people to leave the church, and atheism began to quietly raise its head. The thinking was: if life can arise on its own, then there is no need for God.
However, by the 1960s, knowledge of early Earth's environment had advanced, and it became clear that the early Earth could not have been the same environment Miller had used.[3] Today, most planetary scientists believe early Earth's atmosphere was largely neutral, dominated by carbon dioxide, nitrogen, and water vapour. Subsequent experiments have shown that some amino acids can still form in such atmospheres at much lower yields — but this does not begin to address the deeper problems of life's emergence.
Even if Miller's experiment had succeeded in showing that amino acids could form naturally, that would be an entirely different conclusion from saying that life itself can arise spontaneously.
The fact that soil can form naturally under certain conditions is no more an argument that an apartment building can assemble itself out of nothing. In fact, even if scientists were to place every molecule necessary for a living organism into a single test tube and wait, those molecules would not gather together and become a living creature. It is the same logic as putting every component needed to build a smartphone into a container and shaking it — no matter how long or how hard you shake, they will not assemble themselves into a working phone.
02The odds of amino acids becoming a functional protein
Let us calculate the probability of a single protein forming by chance, since proteins are necessary for life to exist. There are 20 amino acids that help form proteins. Amino acids are made from groups of three DNA base pairs, and the type of amino acid is determined by the sequence and length of those base pairs. Some smaller proteins may contain fewer than 100 amino acids, while in some cases tens of thousands of amino acids are used. Many scientists estimate that an average protein requires around 300 to 400 amino acids.
The critical question is what probability any given sequence of amino acids has of folding into a functional protein. On this topic, molecular biologist Douglas Axe published a paper concluding that the probability of a protein 150 amino acids in length being functional is 1 in 1077.[4]
But that is not all. There are additional conditions required for protein formation.
① Peptide bonding
Each amino acid must be connected by a peptide bond. Peptide bonds form with roughly a 50% probability, so the chance that all 150 amino acids are connected by peptide bonds is 2-149, approximately 10-45.
② Chirality (L-form amino acids only)
Amino acids exist in two mirror-image forms, L and D. Living organisms use only L-form. The probability of a naturally occurring amino acid being L-form is 50%, so the probability that all 150 are L-form is 2-150, again approximately 10-45.
If even a single D-form amino acid is mixed in, or if even one non-peptide bond is present between amino acids, the entire combination collapses and fails to form a protein. Therefore, the probability of a random combination of amino acids accidentally forming even a single protein — not a living organism — is:
This probability is consistent with calculations made by other scientists. Carl Sagan, an astronomer admired by many, calculated the probability of a 100-amino-acid protein forming at 1 in 10130.[5] Professor Gerald Schroeder of MIT calculated the probability of a 130-amino-acid protein forming at 1 in 10170.[6]
Professor Snellen stated that 10 trillion years would be sufficient time for life to evolve — but 10 trillion years is not even enough time for a single protein to form. For one protein to come into existence within 10 trillion years (1013 years), there would need to be approximately 10147 protein-formation attempts every single second.
Everything we have discussed so far concerns not a living organism, but a single protein. So what would the probability of a living organism arising by chance actually be?
03The minimum conditions for the simplest life form
In 2016, Craig Venter's research team published findings on the simplest possible cell.[7][8] In 2010, they had first created a synthetic cell called Syn 1.0, a copy of an existing genome sequence.[9]
The team then attempted to build a cell entirely from scratch on their own, designing one with 480,000 base pairs and 471 genes — but they failed. Eventually, the team succeeded in creating the simplest cell yet, Syn 3.0, composed of 531,000 base pairs and 473 genes.
The team had tried to identify the genes essential for life by eliminating from Syn 1.0 all genes thought to be unnecessary for cell survival. At the outset of this research, they believed that as few as 256 genes would be sufficient.[10] But after decades of research, they identified 473 genes that could not be reduced any further, proving their initial prediction wrong.
Even more striking: around 150 of those genes were clearly essential for survival, yet their specific functions remained completely unknown.
Now let us calculate. We do not know exactly how many proteins are encoded by each gene in the cell the team created. To make the conditions as generous as possible, let us assume there is just one protein per gene. That means the minimum number of proteins required for life is 473. The 531,000 base pairs imply an average of 374 amino acids per gene — but again, we will use the more lenient 150-amino-acid probability for our calculation.
The probability of 473 independent proteins each arising by chance is:
This is why Craig Venter, the lead researcher of the team, said:
We have shown how complex even the simplest life forms are. And these discoveries have humbled us. — J. Craig Venter
04People who came to believe in a Creator after calculating
Several prominent scientists, having confronted these probabilities directly, moved from atheism toward belief in a Creator.
A British astronomer active in the mid-twentieth century and one of the most prominent atheists of his time. Together with his colleague Wickramasinghe, he calculated the probability of life arising naturally at 1 in 1040,000 — and became a theist.
"If one proceeds directly and straightforwardly in this matter, without being deflected by a fear of incurring the wrath of scientific opinion, one arrives at the conclusion that biomaterials with their amazing arrayed complexities were the products of an intelligence. I find no other way to come to this conclusion."
The defining atheist philosopher of the twentieth century — an idol to Richard Dawkins and many other atheists. In 1950, he published a paper titled Theology and Falsification, which became one of the most widely reprinted philosophical publications of the following half-century.
In that paper, Flew argued three main positions: that the universe is eternal, has always existed, and will always exist; that life is the product of random chemical reactions; and that the existence of God is self-contradictory. Yet he ultimately acknowledged that the immense complexity revealed through the advance of science could not be explained within an atheistic worldview, and in 2004 came to accept that this world has a Creator. He explained the change in his book There Is a God: How the World's Most Notorious Atheist Changed His Mind (2007).
A leading scientist in the chemical evolution field during the 1960s and 70s. He set out to scientifically demonstrate that life had arisen naturally — and believed he could do so. But as science advanced, he found it increasingly impossible, and eventually abandoned evolutionary theory to become a creationist.
As he came to understand just how complex even the smallest cells and proteins are, he kept in mind two possible ways of explaining the origin of life through natural science: explaining where the genetic binding originated, or demonstrating that proteins in a primordial ocean could combine amino acids into the correct sequence. Kenyon realised he could do neither. In the late 1970s, he abandoned all of his research that had sought to explain the origin of life through chemical evolution.
05Eugene Koonin's multiverse argument
Despite all of this, many evolutionists still hold to an unsubstantiated belief that life arose naturally. The honest ones admit they cannot explain it. Richard Dawkins himself said in one interview, "Nobody knows how the first living matter came into existence!"[11] They simply refuse to acknowledge a Creator on the grounds of the "God of the gaps" argument.
Some scientists have attempted to explain the origin of life through the multiverse. The prominent evolutionary biologist Eugene Koonin wrote a highly unusual paper in 2007.[12]
In it, Koonin calculated the probability of forming what he called the minimum coupled translation-replication system — that is, the smallest possible system capable of supporting biological evolution. This system requires:
• Ten primitive adaptors (~30 nt each): about 300 nucleotides
• At least one RNA replicase: about 500 nucleotides
Koonin calculated the probability that this entire 1,800-nucleotide system could spontaneously emerge as:
Koonin acknowledged that a probability this low could never occur within the history of our universe. Yet he then abruptly pivoted to argue that if there exists an infinite multiverse produced by eternal inflation, then even an astronomically improbable event like this would be not merely possible but inevitable — and on this basis proceeded to discuss the possibility of life arising naturally.
If an infinite multiverse is real, then events of unimaginable improbability must occur countless times.
Honestly, reading this paper, the only thought that came to mind was: how desperate must these people be to avoid acknowledging God, that such reasoning could find its way into a published paper?
Of course, if an infinite multiverse exists, then any event of any probability — no matter how low — must inevitably occur somewhere. That much is logically true. But two serious problems remain.
Humans have never observed an infinite multiverse, nor can we ever observe one. What is shocking is that a paper in a biology journal could treat the multiverse as established fact and build an argument upon it.
Humans have never observed an event with a probability even as low as 10-50 — which, while extraordinarily small, is still vastly higher than the probability of life arising. If one wishes to argue that a multiverse allows events of staggeringly low probability to occur, then at the very least there should be some observed instance of a comparably improbable event. All manner of seemingly impossible things should be occurring around us constantly.
And yet, the foremost evolutionary theorists make this claim — without any such observation whatsoever. I consider this to be deeply irresponsible propaganda dressed up as science.
06James Tour's chemical critique
One of the most forceful contemporary critics of abiogenesis is Dr. James Tour, a synthetic organic chemist at Rice University. He has authored over 590 research publications and 100 patents, won the Royal Society of Chemistry's Centenary Prize, and is a member of the U.S. National Academy of Engineering — by any measure, one of the world's leading chemists.
In his essay Animadversions of a Synthetic Chemist, Dr. Tour writes plainly:[13]
"It is clear, chemists and biologists are clueless. Those who think scientists understand the issues of prebiotic chemistry are wholly misinformed. Nobody understands them."
"The basis upon which we as scientists are relying is so shaky that we must openly state the situation for what it is: it is a mystery."
— James Tour, Inference ReviewWhat makes Tour's critique especially powerful is this: even in the laboratory, with our most refined instruments and most carefully controlled conditions, no one has built life's molecules from scratch. So how could anyone reasonably claim that uncontrolled, primitive natural conditions accomplished what world-class chemists cannot?
The core problems he identifies:
① Chirality — Natural reactions produce L and D forms in a 50/50 ratio. There is no known natural mechanism that selects only the L-form amino acids that life uses.
② Degradation — Biological molecules degrade as they form. The longer the time, the greater the cumulative loss.
③ Information — The point Tour emphasises most strongly: "The information or coding within the DNA (or RNA) that corresponds to the sequence of the nucleic acids is primary to the entire discussion of life." Chemistry alone cannot account for the origin of information.
07Stephen Meyer and the information problem
Philosopher of science Stephen Meyer, in his book Signature in the Cell: DNA and the Evidence for Intelligent Design (2009), develops this point further into a positive argument.
DNA is not merely a chemical — it is information. And every instance of information we know the origin of comes from a mind.
Meyer's central argument runs like this. The genetic information stored in DNA is not just a chemical pattern; it is a meaningful code, of essentially the same kind as the code in computer software or the words of a sentence. And as far as our experience reaches, the only known cause of meaningful information is an intelligent agent.
Natural selection, Meyer points out, cannot be the answer here. Natural selection only operates on systems that are already self-replicating — but a self-replicating system itself requires information to function. Natural selection therefore cannot explain the information that gave rise to the first living thing.
If neither random chemistry (the probabilities are too small) nor natural selection (it presupposes what needs explaining) can account for the origin of biological information, the most reasonable explanation that remains is an intelligent cause.
08The real motives of those who refuse God
I believe these scientists are fully aware of just how flawed and incoherent their own logic is. So why would such intelligent people insist on making arguments this untenable? In one debate, the answer was laid completely bare.
In a debate with creationist Fuz Rana,[14] the prominent evolutionary biologist Michael Ruse offered these closing remarks:
"I agree with Dr. Rana that the origin of life is a desperately difficult problem. I don't think anyone is going to deny that. I agree with Dr. Rana that scientists today don't have a full answer, or even an adequate answer. There's a lot of what Stephen Jay Gould used to call 'just-so stories' floating around."
"Of course, at first it seemed like it would be easy. But as ten, fifteen, twenty years have gone by, it's become clear that it's much, much harder than anyone thought."
"Surrender and take a Biblical perspective… I always say — if you want to take a Biblical perspective, I can't stop you. But you're not doing science."
— Michael RuseI would rather be a fool than surrender to the Bible. — Michael Ruse, closing the debate
In these remarks, the true inner motives of those who hold an atheistic worldview are laid completely bare. They are not seeking truth — they simply do not want to surrender before God.
No matter how clearly atheists observe that living organisms appear to be designed, they refuse to draw the conclusion that they were designed. Because they do not want to surrender to the Bible. Science as a discipline demands that we set aside our subjective views and preferences when interpreting observations — yet these scientists are violating even that most foundational principle, denying the obvious conclusion to which their own data points.
I can only marvel at the remarkable insight of Scripture — why the Bible says that acknowledging God is the beginning of knowledge, and why it says that those who deny God, though they declare themselves to be wise, have become fools.
For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened. Professing to be wise, they became fools.— Romans 1:20–22
To observe with your own eyes just how complex even the simplest living organism is — to see that it bears every appearance not of something that accumulated by random chance, but of something that was painstakingly and deliberately designed — and then to deny the very conclusions of your own observations: that is the work of a fool.
And the complexity of life that science continues to reveal, the more it advances, is the most powerful evidence we have that the God who created this world is alive — that He made everything for us, and that He made us.
