I'll take a moment to answer several responses to this.
To call Creationism a theory is to miss the correct definition of the word theory. Many people seem to think of theory as a neat idea to explain nature, but that falls far short.
In this case, the key differentiator is that a theory is testable, typically by experimentation. When you claim to have a theory, you'd also better define some sort of experiment or other set of measurements that can prove, disprove, or modify that theory.
From what I've read, Creationism is at the (stoner voice) "Wow Man!" (/stoner voice) stage.
Of course the downside is that there may be no such thing as "string theory", because there seems to be no way to prove or disprove it. To be fair, from what I can see, those who call themselves string theorists are quite upset about that, and would love nothing more than a real experiment.
