I don't dispute that places in the Bible existed. Their is enough evidence to show that most of them did (though, there are a few towns that historians can't seem to locate).
But there is a debate about Jesus. There is exactly ZERO contemporary evidence to suggest Jesus existed. The earliest writings about him were produced 40+ years after his alleged crucifixion. All accounts of him are completely hearsay, not one historian, philosopher, scribe, or follower alive DURING Jesus' life wrote one single thing down about him.
So, there is a debate. I find it very possible he was a great teacher who led a "cult" (as it would be called today), and after he died his followers began spreading tales and eventually he becomes deified. It's not hard to see how it would happen . . . but that doesn't change the fact that there is nothing to suggest he actually existed.
