I think people, myself included, sometimes find it easier to have a discussion about religion, which is universal and fairly easy to grasp, than about a scientific subject that (appears to) require at least some scientific knowledge. It sounds like a really interesting topic but I know I can't really add to a discussion - I've tried the String Theory Simplified link even and although it's not exactly beyond me, I don't want to try and form an opinion when I'm so horribly uneducated on the matter at the moment
