Do we really have the freedom of religion? It was established that their should be a wall of separation between Church and state, and that no religion or belief should be taught in an educational environment. Yet, the government allows evolution to be taught in schools all over the country? I understand excluding religion from curriculum, but if you do this mustn't you also exclude evolution which to many can be seen as a form of religion. It is based on historical discoveries and facts but the implication that it exists and a higher being (which it implies in its teaching instead of religion) does not seems to me a lot like forced beliefs. It is important to stay consistant and allow americans to believe what they wil lrather than raise kids with the belief of a evolution and natural selection which makes any religion seem surreal, because it isnt enforced in schools where children build the foundations of their lives with morals rules and opinions.
