Today in class... Religion in Public Schools

Today in class we had this huge discussion about whether or not public schools should allow prayer and whether or not they should make the lesson on how the Earth was created based on the book of Genesis. I personally think that prayer is an okay thing to allow as long as you allow all prayer of all different religions is allowed and I also feel that it is okay as long as teachers don't make kids pray according to their religion. As far as the lesson on how the Earth is made, I feel it would be okay as long as you incorporated all different religions and how they all believe the Earth was created. If that isn't possible then they should continue the way they are teaching it as of now except they should say that the Big Bang is exactly the way it happened. They should put emphasis on it being a theory.
