Okay, I think we need some clarification here:
The Theory of Evolution states that living organisms will change over the course of generations, since organisms more fit to survive are more likely to reproduce and pass their genes on to offspring. Evolution is well supported by a huge array of scientific evidence.
Intelligent Design states that there is some form of sentience involved in creating life, that sentience is often associated with God, but doesn't necessarily have to be to count as intelligent design.
Now this is what I'd like to point out: one of the two deals with how organisms change over time, and the other deals with how there came to be organsims in the first place. These are in no way opposites.
The "primordial soup" that most of you have probably heard about is not part of the theory of evolution, nor is it supported by very much. The original hypothesis behind this arose due to an experiment wherein a researcher was able to synthesize a few amino acids from chemicals. Even the scientist (I forget the name, I'll update the post if I can find it) who ran this experiment has said that this is not a solid piece of evidence.
