Ok sorry I brainfarted a bit there. There was once a regular bloke called Jesus who was preaching some new ideas and got crucified for it. The rest of the details being spotty.
Obviously there's a big difference between actual Jesus and Astral Jesus who is clearly the more famous of the two.
Anyway back to OP, my vote is for Ronald McDonald.
I mean Tacitus, a Roman pagan historian talks about Christus and his execution by Pontus Pilate. You can be an atheist, accept Christ was a real historical figure but not divine. I certainly do.
