I just totally owned an Athiest Co-Worker.

Ok first of all, I know it's not right to be prideful, but he was so arrogant about his dis-belief in God, and that anybody who did believe was 'mentally unstable' and needed to be 'kept away from "decent folks"'

We got into a discussion in the break room, and the subject came up to God, and he knows I am a Christian. He said 'How can you believe in something you have never seen before... you don't even know that God exists. You think he does, based on what some stupid book (the Bible) says, but you can never know for sure.

So I used his own logic against him. I said 'And by that token, you can't prove Christopher Columbus existed, because you've never seen him. He just rolled his eyes and said 'Anybody with a brain cell... even you can't tell me he didn't exist. Everybody knows he left Spain and discovered the New World.

I just smiled and said 'But you don't know for sure. You're just going by what the history books have said unless you see it for yourself, there is no way you can prove it. Those were your exact words' .

He didn't like me putting his own words back to him, so he just left and didn't speak to me for the rest of the day.
