Being the evolutionist you are, I'm sure you're familiar with uniformitarianism. To be sure we're on the right page, here's an excerpt from Wikipedia:
Uniformitarianism, in the philosophy of science, assumes that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe. Its methodology is frequently summarized as "the present is the key to the past," because it holds that all things continue as they were from the beginning of the world.[1]
So, if the present is the key to the past: what do we know today about information that can teach us about ID? We know that information only comes from an informer. You can't find website markup, a book, or a computer without a designer -- all these things contain information.
In the same way, our dna contains information. It can be replicated, read, and even examined for mistakes. Here's a short presentation on the topic: http://www.youtube.com/watch?v=1fiJupfbSpg
Therefore, the information in our dna proves that an informer put it there sometime in the past.
