Any time someone asks me if I believe in god, I ask them to define that word... and since 75% of them cannot define "god" in any understandable sense, I ask them how I am suppose to believe in something, they themselves cannot define. It usually ends any debate or bad feelings right away.
I'm not 100% sure that I really exist, so I can't make any absolute statements about anything else. I am pretty confident that the buybull ghod is omni-aqueous, though. (All wet.)
