Jesus, however, is an interesting case. I can't really say I believe in him or do not believe in him. Until we get some time travelling going, as far as I know which we haven't yet, I'm going to say he just was any other guy in history and I could care less.
Probably a clever person, someone who could easily deceive people, maybe even a "magician" if you like. Back in those days people didn't question stuff like that, were more gullible. Probably wouldn't have been hard.
The only logical answer to the poll is 'there's no way to tell'.
How can you prove that he's real - but then again how can you prove that he's not?
There is absolutely no evidence of God in the definition that Christianity gives to him. God is a human creation, written by and for human-beings. We can't disprove it, because it was crafted in a way to stop you from disproving it. Its setup so its too awkward to be disproven.
There are many versions of God, and many religions. Each religion contradicts the next one. Yet everyone thinks what they believe in is the "right" God and religion.
