There is no historical proof, outside the bible, that a man named Jesus was creating such havoc during those times. And of course, the earliest writings from the bible weren't written until 200 years or so after Jesus allegedly died.
The romans documented things quite well too. Perhaps the Romans burned any mention of the man, but we'll never know for sure if that is why no proof has ever been found.
I do not believe in Jesus but have no problem with those that do. His "bio" has too many similarities to other folks who pre-dated him by 100's if not 1000's of years. All born of virgins, son of God, performed miracles, died on a crucifix,etc etc to be a coincidence.
