Ouch. I hate it when I see this kind of thing. Similar to the concept of "debating" God. It really is a worldview issue. I can't, and won't, say atheists are wrong. I will say, that for me, in my experience, I do feel there is a God. Not necessarily of the robed and bearded sort, but something there.
It boils down to the way we answer question of the origin of life:
Is there a reason?
A Christian says yes. There is a reason, and there is a God, something beyond experience that created that reason and exists for the purpose of relationship between the creator/the created.
An atheist says no. Everything is random. WYSIWYG.
... Neither position can be verified as accurate in some quantifiable way. I know what is part of me, personally, and beyond that, I can't say. I don't see how these two viewpoints can "debate". Discuss, maybe, but there isn't much room for debate. Neither side will EVER see it the same way...both could talk til' they're blue in the mouth.
Insults like the OP with the so-called "wit" about the "stupid-atheist-professor" do nothing positive for either side and only further divide people who might otherwise be able to have an interesting chat. Frankly, it bums me out.
