The burden of proof lies on the person making a positive claim. That's you.
None.
No, I believe in things which I have a logical reason to believe in. I've seen videos of WWII, heard first hand accounts, and seen multi-million dollar monuments. I believe it happened.
The crucifixion, I also believe happened. For similar reasons.
None.

A point so valid I feel it needs to be repeated:No, I believe in things which I have a logical reason to believe in.
I'm sure many of the events of history "we" consider correct are true. I'm also equally sure any portion of history could be incorrect. If there is more evidence for something there's a greater possibility that it is true.
As for the bible, I'm sure after countless translations and intentional revisions people have distorted the words enough so that some original meanings drastically changed. Do I think Jesus lived and taught? Yes. Do I think he came back from the dead? No. I'm not an expert on the subject, but I remember that there are several conflicting stories about Jesus' resurrection coming from "primary sources."

Kinda like telephone...You know, the game where you sit in a circle, whisper in someone's ear, and pass the message along until a funky version gets back to the beginner.
I tend to believe things that either are credible or I have experience in. Prudence is key--I don't really believe in any religion because if something has to be "revised" or "edited" all the countless times it has, not much of the original content can be preserved.
