No, it isn't, although "controversial" was not what I addressed in my post. Just because a few kooks don't believe it, or the moon landing, doesn't make them any less valid.
The main controversy in the teaching of science, to me, is when it takes an atheistic, rather than an agnostic-ish, position.
What exactly is the difference? The subject of God is so far outside the scope of a high school science class I can't figure out why this is even a consideration.
