On June 26, 2000, at a White House ceremony broadcast worldwide, President Bill Clinton announced the completion of the first draft of the human genome. His words stunned many: "Today, we are learning the language in which God created life." Standing beside him was the scientist who led the project - Francis Collins - a former atheist who had become one of the world's most prominent Christian voices in science.
The Human Genome Project was a 13-year international effort involving 2,400 scientists to map every letter of human DNA - all 3.1 billion base pairs. When the first draft was completed in 2000, it was announced in a ceremony featuring President Clinton, Prime Minister Tony Blair (via satellite), Craig Venter of Celera Genomics, and Francis Collins, director of the public Human Genome Project.
Clinton compared the genome map to Meriwether Lewis's map presented to Thomas Jefferson in that same room two centuries earlier. But what captured the world's attention was his next statement: "Today, we are learning the language in which God created life."
Collins followed with his own remark: "It is humbling for me, and awe-inspiring, to realize that we have caught the first glimpse of our own instruction book, previously known only to God."
These were not casual figures of speech. Collins - who had converted from atheism to Christianity after reading C.S. Lewis - meant exactly what he said. He went on to write The Language of God, a bestselling book arguing that the genome reveals the signature of a Creator.
When scientists describe DNA as a "language" or "code," they are not using metaphors. DNA is an information-storage system that operates with the same structural properties as human languages and computer code:
Here is the critical point: in every other domain of human experience, information encoded in a language - books, computer programs, blueprints - is always the product of a mind. We have no known example of a language or code arising from purely physical, unguided processes. DNA is the most complex information system in the known universe. The question is: where did the information come from?
Collins wrote: "I cannot see how nature could have created itself. Only a supernatural force that is outside of space and time could have done that." And: "In my view, DNA sequence alone will never explain certain special human attributes, such as the knowledge of the Moral Law and the universal search for God." For Collins, sequencing the genome was not a threat to faith - it was an act of worship.
When the chimpanzee genome was sequenced and compared to the human genome, researchers found approximately 98.7% similarity in coding DNA. This figure is often cited to minimize the difference between humans and chimps. But the number requires context:
A 1.3% difference across 3.1 billion base pairs equals roughly 40 million base-pair differences. That is 40 million precisely placed "letters" that must be in the right sequence to produce a human rather than a chimpanzee. The functional differences between humans and chimps - language, abstract reasoning, moral awareness, art, mathematics, spiritual consciousness - arise from this seemingly small percentage. The information encoded in those 40 million differences is what separates a creature that paints the Sistine Chapel from one that does not.
Collins's story matters because he did not come to faith despite science - he came to faith partly because of it. As a graduate student in quantum mechanics at Yale, he was an atheist. During medical school, watching patients face death with extraordinary peace rooted in faith, he began to question his assumptions. Reading C.S. Lewis's Mere Christianity shattered his confidence in atheism. He converted at age 27.
For Collins, the Moral Law - the universal human sense of right and wrong - was the most compelling pointer to God. But the genome deepened his conviction. The elegance, the information density, the sheer complexity of the code that builds a human being struck him not as evidence against a Creator but as a window into how that Creator works.
"Calling DNA a 'language' is just a metaphor. It's chemistry, not communication."
DNA is not merely described as a code by analogy - it functions as one. It has an alphabet (four bases), words (codons), grammar (reading frames and regulatory sequences), and it transmits specified information that directs the construction of proteins. These are the formal properties of a language. The question is not whether DNA is a code - that is settled science. The question is whether codes arise without intelligence. In all human experience, they do not.
"Collins accepts evolution - doesn't that undermine the design argument?"
Collins accepts that God used evolutionary processes as His method of creation - a position called theistic evolution or BioLogos. He argues that evolution does not explain where the information in DNA came from in the first place, nor does it explain the Moral Law, consciousness, or the fine-tuning of the universe. For Collins, evolution is the "how" - God is the "who" and the "why." One can debate the mechanism while agreeing on the deeper point: the information in DNA points to a mind.
Why is the "language" description of DNA more than just a metaphor?
The human genome is a 3.1-billion-letter information system that encodes the instructions for building a human being. DNA functions as a genuine language with an alphabet, words, grammar, and specified information. In every other domain of experience, such systems originate from intelligence. The scientist who led the project to decode it - Francis Collins - concluded that the genome reveals the language of God.
