No, there was reference to him in Joephus and Tacitus. The single stone with his name found in the 60s corroborates his existence.
But none of the biblical stories are confirmed.
Just as the existence of a man named Yeshua doesn't mean anything in the Bible really happened.
Look maybe Jesus was real and some of that stuff happened, maybe it didn't.
I just had a problem with questionable events being a fixed point in time. Of course to follow this show I have to the accept the spear of destiny, which is definitely a myth. And that the fake artifacts from the Crusades are real. So I guess this show is just Christian fantasy.
