How DNA, information theory, and the code of life all point to a Designer
The Big Three — What This Article Covers:
1. DNA is not just chemistry — it is best described as a coded information system. And in all our experience, codes and information systems come from minds.
2. No experiment has ever produced a fully self-replicating, digitally coded information system like DNA from raw matter alone. Partial steps exist. The full system does not.
3. The God who spoke the universe into existence also wrote the code of life. Genesis says He did. The evidence agrees.
A Message in a Bottle
Imagine you are walking along a deserted beach. The sand is smooth, the waves are steady, and nothing suggests another human being has been here in weeks. Then you look down and see letters scratched into the sand: HELP ME. STRANDED ON NORTH POINT.
You would not for one second assume the waves wrote that message. You would not credit the wind. You would not wonder whether random erosion happened to carve out English words in the right order. You would immediately recognize that a mind produced that message — because messages always come from minds.
Now imagine discovering that every single living cell on earth — from the simplest bacterium to every cell in your body — contains a message far more complex than anything scratched in sand. A message written in a four-letter chemical alphabet. A message carrying the precise instructions to build, maintain, and reproduce a living organism.
That message is DNA. And the question this article will answer is simple: Where did the message come from? It is the next reason why a scientist believes in a Creator — and it may be the most powerful one of all.
What Everyone Already Knows About Information
Before we talk about biology, let us talk about something far more basic — something every person on earth already understands.
Information is not the same thing as matter. A book is made of paper and ink, but the information in the book is not paper and ink. You can burn the book and destroy the paper, but the information can survive — copied onto another page, stored in a computer, or memorized in someone’s mind. The message is not the medium.
This is not a philosophical trick. It is an observation you act on every day. When you read a text message, you do not analyze the electromagnetic signals that carried it. You read the words. You understand the meaning. And you know — without even thinking about it — that a person sent that message. Signals do not compose themselves. Codes do not write themselves. Information does not arise from raw materials any more than a dictionary assembles itself by shaking a box of letter tiles.
Bill Nowers, a longtime Virginia Christian Alliance advisor, used a simple illustration that cuts right to the point. If you were walking along the beach and found the words “John loves Mary” scratched in the sand, nobody would deny that some intelligence was involved. Yet those who believe in evolution claim that all life — with its unbelievably complex microscopic cellular structure — just happened by chance.
The principle is as solid as anything in science: in all known cases, specified, functional information — the kind that carries instructions and executes commands — traces back to an intelligent source. Nature can produce order. Crystals form. Snowflakes arrange themselves into patterns. But order is not information. A repeating pattern is not a blueprint. No natural process has ever been observed producing a full DNA-style system of coded, functional instructions from simple chemistry alone. Partial steps and ordered structures exist, but nothing on the level of the genome in even the simplest cell.
The Best Case for a Natural Origin of Biological Information
Intellectual honesty requires that we present the strongest version of the opposing view before examining it.
Proponents of naturalistic origins argue that the chemistry of early earth — given the right conditions, enough time, and enough energy — could have produced self-replicating molecules. The most widely discussed model is the RNA World hypothesis. It proposes that RNA molecules capable of both storing information and catalyzing chemical reactions preceded DNA and proteins. Over vast stretches of time, natural selection acting on random mutations could have built increasingly complex biological systems.
This framework has real scientific work behind it. Researchers have demonstrated that some of the chemical building blocks of life — amino acids, nucleotides — can form under certain laboratory conditions. The Miller-Urey experiment in the 1950s showed that electrical discharges in a mixture of gases could produce amino acids. More recent experiments have extended these results.
These achievements are real and deserve fair acknowledgment. The researchers involved are serious scientists doing careful work.
But producing the building blocks of life is not the same thing as producing life. And producing chemicals is not the same thing as producing information. That is precisely where the naturalistic account runs into a wall it has never overcome.
Where the Explanation Breaks Down
Here is the problem, stated as plainly as possible: unguided chemistry has not been shown to produce a full DNA-like system of specified, digitally encoded biological information by itself.
DNA is not merely a complex molecule. It is a language system. It uses a four-letter chemical alphabet — adenine, thymine, guanine, and cytosine — arranged in precise sequences that carry specific instructions. The sequence matters. Just as the letters C-A-T mean something entirely different from A-C-T, the order of these chemical “letters” determines what proteins are built. It determines when they are built and how they function.
This is more than a loose metaphor. Molecular biologists routinely describe transcription, translation, and error correction because DNA really does function as an information-processing system — even though its “meaning” is implemented through chemistry rather than conscious understanding. The cell processes DNA the way a computer processes software. It decodes instructions, executes them, and builds structures according to a blueprint it did not write.
Consider the scale of what we are talking about. A single human cell contains approximately six feet of DNA packed into a space one-thousandth of a millimeter across. That DNA carries roughly 3.2 billion base pairs of coded information — the equivalent of about 750 megabytes of digital data. Every cell in your body carries a complete copy of this code. And the human body contains approximately 37 trillion cells, each one running this software continuously.
No experiment has ever produced a fully self-replicating, digitally coded information system from raw chemistry. Researchers have demonstrated partial steps toward self-organization and catalytic activity — and that work is real. Some labs are even approaching primitive “protocell” systems that grow, divide, and replicate simple genetic polymers, although these are still far from true cells. But partial steps toward a system are not the system itself. The Miller-Urey experiment produced amino acids — building blocks. But building blocks are not buildings. Bricks scattered on a lot are not a hospital. Letters dumped from a bag are not a novel. Even with these advances, there is still no demonstrated pathway from such simple systems to the integrated, digitally encoded, error-correcting information architecture of even the smallest free-living organism. It is a gap of kind, not degree.
Even the simplest known self-replicating organism — Mycoplasma genitalium — requires approximately 580,000 base pairs of DNA and around 470 genes to function. And this is a streamlined modern parasite, not an early “proto-cell” — the first life would still need enough information to sustain metabolism, replication, and repair. There is no known pathway from nonliving chemistry to that level of organized, functional information. The origin-of-life research community acknowledges this openly. Nobel laureate Jack Szostak has noted that the transition from chemistry to biology remains one of the great unsolved problems in science.
The late Bill Nowers put the problem with characteristic directness: the very foundation of the entire evolution belief rests on the assumption that life arose from dead matter. He called it a foundation hanging in the air with nothing under it. Decades of research have not changed that assessment.
Why Information Demands a Mind
If chemicals do not produce coded information, and coded information is exactly what we find in every living cell, then where did it come from?
The same reasoning we applied in our first article on cause and effect applies here. Every effect requires a sufficient cause. The effect we observe is not just complexity — complexity can arise from simple physical processes like crystal formation or snowflake patterns. What we observe is specified complexity — information arranged according to a code, carrying functional instructions, and subject to error-correction mechanisms.
In all of human experience, specified information of this kind comes from one source and one source only: a mind. Software comes from programmers. Books come from authors. Blueprints come from engineers. Languages come from intelligent beings who assign meaning to symbols.
This is not “God of the gaps.” We are not saying “science can’t explain it, therefore God.” We are saying that what science has discovered — that life runs on coded information — points directly and positively toward an intelligent source. The deeper molecular biology goes, the stronger the case becomes. Every new discovery about the cell reveals more layers of information processing, more error-correction systems, more precisely coordinated machinery.
The argument is not from ignorance. It is from knowledge. The more we know, the more a Designer becomes not just plausible, but necessary. This is why a scientist believes in a Creator — not because science has run out of answers, but because the answers it has found point unmistakably toward a mind.
Why a Scientist Believes in a Creator: The Author of the Code
The Bible does not use the word DNA. But it describes a God whose creative method is entirely consistent with what molecular biology has uncovered.
Genesis 1:1 tells us God created — a deliberate, intelligent act. But look at how Scripture describes His creative method: “Then God said, ‘Let there be light,’ and there was light” (Genesis 1:3). God spoke the universe into existence. He used language. He issued commands. And matter obeyed.
This pattern runs through the entire creation account. “God said… and it was so.” The Creator is not a blind force. He is a communicator — a God who encodes His will into reality through information.
The apostle John makes this explicit: “In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made” (John 1:1–3). The Greek term John uses — Logos — means word, reason, logic, information. John is telling us that the source of all things is not impersonal energy but personal intelligence. The Word — the ultimate information source — is God Himself.
And Paul confirms that this Creator left His fingerprints everywhere: “For since the creation of the world God’s invisible qualities — his eternal power and divine nature — have been clearly seen, being understood from what has been made, so that people are without excuse” (Romans 1:20).
The Virginia Christian Alliance holds to the biblical account of a six-day creation by the God who spoke all things into existence. DNA — the language written in every living cell — is not an argument against that account. It is evidence for it. The code demands a Coder. The language demands an Author. And Scripture tells us His name.
David understood this long before the microscope existed: “For you created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well” (Psalm 139:13–14). David did not know about DNA, base pairs, or protein synthesis. But he knew the same truth molecular biology has confirmed. The design written into every human body is the work of a personal, purposeful Creator.
What Will You Do With This?
Dear Christian: The next time someone tells you that science has made God unnecessary, ask them one question: Where did the information in DNA come from? Not the chemicals — the information. The code. The language. Watch what happens. There is no naturalistic answer to that question, because information does not write itself. You do not need a biology degree to see this. You just need the common sense you already have. No argument on a page can change a heart — but the God who wrote the code in every living cell can. Trust Him with the conversation.
Dear skeptic, dear seeker: You live in a body running on software you did not write. Every cell in your body is reading, copying, and executing coded instructions right now, as you read this sentence. That code had to come from somewhere. If information always comes from a mind — and it does — then the mind behind your DNA is beyond anything human engineering has ever approached. Follow that logic honestly. See where it leads. And if it leads you to a Creator — do not be afraid. The Author of the code in your cells is also the Author of the invitation: “Come to me, all you who are weary and burdened, and I will give you rest” (Matthew 11:28). He is not far from you.
The battle is real, but so is our God. “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalm 19:1). And so does every strand of DNA in every living creature on earth. This is why a scientist believes in a Creator — and why the code of life should give every honest thinker pause. We stand firm, speak truth, and trust the One who holds all things — including the code of life — in His hands.
