That is why it is important to say that religion most certainly does not belong in public schools. In addition, religion should not be in public schools because it is false . As atheists, we frequently ignore or do not even consider that point. Religion is false. Evolution should be taught in biology classes, creationism in humanities.
Evolution is a fact, creation is a myth.
Public schools should be neutral about the existence of a god, even if everyone were to agree that a god existed. This is not to say that lively debate should not occur in public schools. Far from it, I discussed the non-existence of God as part of a presentation I did in my AP English class on Dante's Inferno. I argued with my fundamentalist friend in class as well. But the government did not sponsor my presentation, nor my discussions with my friends.
