Funny thing is that it's not logical. The creationists are starting off with a logical fallacy (false dichotomy) at the basis for their strategy to get converts. They have not even tried to do scientific study to produce positive evidence of ID, just tried disproving evolution.
Okay, fine, let's say evolution is found completely false and falls apart as a scientific theory. Then these 'neo creos' they'll think they've won, and believe ID is the only scientifically acceptable answer. WRONG, they've started with a false dichotomy and produced no evidence for their side. At that point, there will be NO scientific theory as to our beginning.
For sure, a false dichotomy, but you can understand them thinking, "First, we have to destroy what's there."
"The Un-Discovery Institute" would be a better term.
