Why should both be taught in science class when only one is scientific?

This is like saying we should teach both astrology and astronomy in science class.

I fail to see how I'm creating a problem that's not even there, but maybe you guys don't have this problem in Sweden. Here in the US some religious groups are trying to get evolutionary education outright banned from schools, and trying to force schools to teach religious beliefs in science classes (i.e. Creationism).

I didn't create the problem, they did. I'm just commenting on my frustrations with it.
