Once again I hear people coming up with that remark Jesus didn't exist. That he is someone made up to explain a belief system that has no validity.
Well, Jesus is a man of history..
There is just too much evidence for the historicity of Jesus-- more so than for the historicity of a person called Julius Ceaser.
Even outside the four gospels we have the accounts of Polycarp, Eusebius, Ignatius, Justin and Origin.
There were no that far removed from the time of Jesus.
Tacitus, born A.D. 52-54, writing in the time of Nero refered to a person named Christus who was put to death by Pontius Pilate, a procurator of Judea in the reign of Tiberius.
Josephus born A.D. 37 wrote "There was about this time Jesus, a wise man, if it is lawful to call him a man."
I will not bore you with more. You get the idea.
And it was this Jesus who claimed to be the Son of Man ( a reference to the Jewish Messiah)
Just saying that Jesus is a man of history
