You are so right! The irony here is that it takes as much “faith” (if not more!) to believe in evolution as it does to believe in a creator. Since neither can be proved by traditional scientific method (observation, testing of hypotheses, and ability to re-create the conditions to verify results), some have seen fit to re-define the term “science” in an attempt to promote their particular theory. Evolution is just that - a theory. Why should it be given more prestige than it deserves?
"Critical thinking" is a creationist propaganda line designed to sneak a narrow fundamentalist view of religion into science classes.
Real critical thinking is absolutely the last thing creationists want applied to their beliefs. But under this new law, look for exactly this to happen -- and there is nothing they can do about it.
