You are arguing with me that he for sure didn't exist. We're not arguing the same point, and I already said he very well might be historical fiction. The myth of Jesus, however, exists. And the fact we have letters from the first century that specifically talk about him makes him an historical figure. Also, and this is my opinion, it's not that far fetched that a person lived in the middle east 2 thousand years ago, started a cult of personality and the regurgitated stories about him passed from generation to generation. We also can't deny that by the 3rd century the Roman empire was full of his followers (Catholicism was made the official religion in 381, so the spread has to have started earlier), and as with everything in our planet, the jesus fandom has to have started somewhere sometime. Using Occam's razor, the most simple solution is a man in the middle east gets popular doing populist things, he gains followers doing this and after becoming ubiquitous, his followings get institutionalized by one of the most influencial empires in human history and now he's become universal. You can make a religion out of this.
