EVIDENCE:
For now, I'll mention two pieces of evidence. The moderators may throw this out, but I think it relates directly to this.
One:
I put forth Jesus as evidence of the supernatural. He claimed to be God.
So you've got three choices:
he was God
he was lying
he was crazy
If you read the gopsel accounts, it's absolutely impossible to say he was crazy. The things he said, did, and the way the people around him responded do not allow for a crazy man. If Jesus were a liar, why would he die for his claim, when he could easily have avoided such a cruel death with a few choice words? (By the way, this rules out the option of his just being a "good man" or "good teacher". If he's lying, he's not a good teacher, otherwise he's God or crazy)
The other piece of evidence involves morals/ethics. I refer you to my post in that section for this:
