Thanks for your comments Paul. I guess my reply would be that not believing in something because there is no evidence is not the issue. It is believing it does not exist because there is no evidence. There is no reason to believe in pink elephants, but there is also no basis for categorically stating that they do not exist. I'll grant you that it's a very subtle difference, but in my opinion it's a very important one.

I don't believe in the Christian God, or indeed the God(s) from any organised religion, but I cannot say that science proves they don't exist because it doesn't. To say it does is to misrepresent science and to take a leap of faith of sorts.
