They can both be science, a lot of the bible has been proven by scientists. Personally I think if they are going to teach evolution then they should also teach creationism. Then let the student decide which one he or she thinks is right. If people really want to get pissy over what their kids are learning then they can teach their kids themselves. It's not like having both in a text book is going to teach kids wrong, it is just teaching them more than one possible way of how us as human became to be. It's like teaching a student more than one way to solve a quadratic equation, there are more than one way to do it, and one way works better on some things than the other way. For example some things are not specific enough in the Bible or other Religious texts to prove something. But then again something taught in evolution isn't good enough to prove it, i.e. missing links in the chain. But then again this is just my opinion, someone may have said stuff along these lines, but this is what I have to say. So flame me or not, don't give a crap.
