Personally I think both the creation story of the religous majority (of the city/town/province/district) and evolution should be taught at schools. However the creation story should be taught in a religion class and evolution should be taught in a science class. Also the unit on evolution as well as creation story should be optional and those not wanting to hear a specific side of the argument and should be able to opt out of the unit at any time. I also believe that these subjects should only be taught at a higher grade level when they can create their own intelligent opinion on the subject.
