That’s a terrible argument. That was one pharaoh and the monument would have been finished within his lifetime if he had lived a normal lifespan for a pharaoh… Most Pharaohs had monuments to them- not just tombs, but temples- built within their lifetime. We know because they tell us so right on the walls.
And, again, I was talking about the Jesus of the Bible, which is obviously who OP is asking about. That Jesus, who has magic powers and is the son of a god, did not exist. So there is no evidence for him even if he was based on a real person. A point you are still missing because you seem to think I am saying that there was no real person the character was based on, I am not. I thought I made that clear when I mentioned Bloefeld.
If there was a real Jesus, we have absolutely no idea what, if anything, said about him in the Bible actually happened or was something we said because there is no evidence of it outside the Bible and the Bible cannot be trusted. Which is why I maintain it doesn’t matter if the Jesus of the Bible was based on a real person, because it tells us nothing about that person that we can confirm as being true.
So, to answer OP’s question, there is no real physical proof that Jesus Christ ever existed. The name OP gives is a hint. “Christ” means messiah and “Jesus” is the Greek version of the name. A real Jesus would have a name similar to Yeshua and his full name would have been similar to Yeshua bin Yosef. Nazareth might be appended to the end. That wasn’t who OP was asking about though. They were asking about a messiah.
