We don’t really have evidence of Jesus’ historicity. I mean absence of evidence isn’t evidence of absence but, all in all, there’s pretty much zero direct evidence of his existence. Almost nothing that would point to historicity in the gospels is corroborated by archeology… like was Pilot a person who existed? Yes, very likely he was. Is there biographies of him? Yes, there are contemporaneous sources showing him to be real. Is there anything, outside of the gospels, recount him meeting Jesus in any capacity let alone a whole trial and execution? No, there’s nothing like that. The whole scenario of Jesus’ life as chronicled by the gospels doesn’t hold up to scrutiny… sure, some of the people and many of the places do exist, but just because New York exists it doesn’t mean Spiderman is real.

As for the early church, even Paul doesn’t claim to have known a historic Jesus but rather only recounts experiences of visions of Jesus and angels.
