I agree that an alternative religious figure probably existed, but I was talking about the existence of the purported biblical Jesus.
We can speculate a cult leader or preacher existed. We have no evidence that he did the deeds narrated in the Gospels. I'm all for historical curiosity. However, this small piece of information is not terribly relevant to faith and religion. In particular, it's not relevant to a claim like the one made by the AC to which I replied (the claim that we have evidence of Jesus' resurrection).
