The Atheist Dilemma

[Setton]

One can not prove a negative (that something doesn't exist).

Actually that's exactly what you're meant to do in science. Say you've got five ideas, disprove four and you have your best answer. The trouble is, as Rlyeh says, God doesn't exist in nature science. If I'm on the same page as him, this is because the idea of God is not testable or falsifiable. By its very definition, it cannot be proven true or false so asking evidence either way is rather pointless. It's just not science and doesn't belong or fit in a scientific debate.
