Why the Information in Our DNA Points to the Existence of God
by J Warner Wallace
The more we learn about the origin of life in our universe, the more reasonable the case for God’s existence. The building blocks of life (proteins, ribosomes, enzymes etc.) are formed at the direction of specific nucleotide sequencing in DNA, the largest molecule known. In humans, DNA contains as many as 10 billion atoms. The adenine, guanine, cytosine, and thymine bases in DNA are linked in a particular order to form the genetic code containing the master plan for every organism. The information in DNA guides and instructs the formation of proteins; without it, protein formation would be a haphazard, hit-or-miss proposal. The nucleic sequence in DNA is informational.
Physicist Paul Davies expresses it well: “Once this essential point is grasped, the real problem of biogenesis is clear. Since the heady successes of molecular biology, most investigators have sought the secret of life in the physics and chemistry of molecules. But they will look in vain for conventional physics and chemistry to explain life, for that is a classic case of confusing the medium with the message. The secret of life lies, not in its chemical basis, but in the logical and informational rules it exploits.”
Information in RNA and DNA presents a problem for researchers, especially those who propose RNA as the first molecule to appear through some combination of chance and chemical necessity (known as the “RNA World Hypothesis”). Even if RNA is a precursor to DNA, the first RNA molecules would have to be rich in information to replicate. Information must exist first, before any other transformational process can take place. Without the prior genetic information in DNA and RNA, nothing of significance happens within cells.
Nucleotide sequences are more than statistical gibberish. They are semantically, pragmatically, and apobetically significant sources of information (for more information on these categories of information, see my new book, God’s Crime Scene). The genetic sequence has meaning and directs action for a specific purpose.
Our personal experience tells us information comes only from intelligent sources. In fact, in the entire history of the universe (and the history of science) a single instance of information arising from anything other than intelligence has never been identified…
