As a non religious purpose I find it just does not make sense that the universe needs some kind of supernatural element for it to work.
The thing with arguing with people who believe is that they honestly believe what they say i.e. that the supernatural exists.
But it is only fundamentalists (as a subset of people who accept the existence of the supernatural) who get all bent out of shape about it.
Growing up going to a C of E school when we had religious education the 'controversy' was never mentioned at all.
