The process of thought that Gene also wants to use as evidence is the "it's a code similar to those constructed by intelligence" argument. The only problem with this argument is:
1. The codes used for the inference are created by natural creatures (Humans) by natural methods. No supernatural code has ever been found.
2. Therefore, DNA code can only be inferred as being created by natural forces, not supernatural. It asks the question of who designed the first designer without anything to produce the first designer.
As many IDists ask: "Provide evidence of a code arising from natural causes," they still haven't supplied the proof of a supernatural code arising in the natural world.
