I've had orientation in my department all day and it's taken a while to settle down and catch up.
First, it's quite presumptuous of you to tell me I don't believe in God.
Second, your sarcastic post made little sense. I study computational math, and I'm interested in physical modeling. All those games and movies you watch which use CGI, most of those are based on physics engines. The simple facts that the algorithms we create to approximate nature are designed and the computers we use to integrate these algorithms are designed make no statement as to the "design-edness" of the system being modeled - we attempt to recreate natural events from initial conditions as closely as possible using the fundamental principles and forces of nature... without intervention.
Your analogy is wrought with falacies. I'll name a few:
1. the "Fitness function" of biological evolution is not designed, it is completely circumstatial and arbitrary.
2. nature provides a very effective means of determining which "programs won't compile" - death. In the analogy, the decision algorithm required is actually undecidable - Halting problem reduction.
3. The rest is even more absurd jibbering, which I won't address. I'm not partial to analogies... way too easy to fall into falacies.
Which brings me to my last point. Interestingly, the one thing I find missing most from these threads is... biology. Being an applied mathenatician, I prefer to apply theories to toy examples and get used to how they function, what are some common pitfalls, and how they may be overcome. One of my favorite links is a list of these specimins:

Now, the knee-jerk reactions to the Blind Cavefish:
Creationist: Why are you questioning god's... I mean the creator's... judgement?
Biologist: This fish is likely the descendent of a freshwater fish which had eyes. A population of these fish likely broke off and found a niche - a place where they could live with little competition - in a cave. A good place to start would be to try and find "cousins" of these fish. We do this genetically and morhpologically.
