The reason I said to look up Mithra was that the story of Jesus follows an uncanny resemblance to that of Mithra.

Indeed, there was probably a man named Jesus, possibly even a preacher. It was actually a fairly common name at the time.

There is no proof of Jesus's existence. Nor is there proof of Thor. Thor is more interesting in my own humble opinion, and Thor is also more original (look up Mithra, if you don't believe me, or Dionysus)
