Evolution isn't science; it's a theory and nothing more. (That's why it's called "The THEORY of Evolution". Of course actual science should be taught in school, but not the fairy tale elements. If people want to believe in evolution on the basis of faith, as do those who believe in creationism, fine, but there's no proof in either.
My point is there's NO science that's proven, so if proof is your standard, we should teach no science at all. The theory of evolution is a theory because that's all it can and will ever be, no matter how much evidence is gathered. Theories don't become facts, laws or anything other than theories.
