When we talk about codes, we are talking about information. Our DNA represents the information that makes up each and every one of us. Dr. Dembski has already shown that this code is complex and specified information, so I won’t go into that here. But, what I do want to touch on is that this code is much like a computer program. The language of DNA – Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) – can be thought of as the ones and zeros that make your computer run, just in base 4 instead of binary and using letters instead of numbers. And, just like a computer, this language is used to create the many programs that we see all around us as living organisms. It makes more sense to think that someone would (and did!) use this program to create life, simply changing the bits here and there to create different programs (organisms) just as one changes bits here and there to create different programs in any programming language.
Materialists, however, would have us believe that through trial and error that nature hit upon this program and was continually able to use it, all by chance. This is highly unlikely and we know of no other code that happens in this manner. All codes, all languages, and all programs are as the result of design. Common design is the only hypothesis of the two that has been shown and is clearly the better in this case.
