You're kidding right?
Of course he isn't kidding, it's a fair question and simply pretending that it's a silly question does your arguments no favours.
The fact is, although the Bible contains historical places (and possibly even some historical events) so do the Harry Potter novels, and like the Harry Potter novels, the stories within the Bible that involve miracles or magic can never be shown to be factual. For this reason, we can only consider such stories as fictional, mythological, or legendary at best.
Jesus
may have been a real person, or possibly the character of Jesus might have been
based upon a real person, but we can only rationaly consider that in the same way that the character of King Arthur
might have been based upon a real person. There are plenty of historians who consider that Arthur could well be based upon a genuine historical figure, a Romano-British leader who fought against the invading Anglo-Saxons sometime in the late 5th to early 6th century, many even consider that Arthur's legendary advisor Merlin could also be based upon a real person, but not one of them seriously considers that Merlin was a wizard who could actualy do real magic.
Historicaly, at best, we can rationaly consider that it's possible that Jesus might have existed as a person, possibly a first century teacher of morality who taught via parables in Judea, in a similar vein to the Greek Aesop, but there's no rationality whatsoever in considering him as a supernatural miracle worker who was immune to death.
