I will just Post this comment from Quora ( feeling lazy) and see what Sea Breeze has to say:
" While there is a minority of historians who claim that there never was a Jesus, the vast majority believe there was a Jesus, but completely disagree to what extent all the tales about Jesus were actually discussing the same individual. This is primarily due to the scarcity of valid, reliable information regarding Jesus.
- The author is unknown; sometime in the 2nd century CE, Papias of Hierapolis began saying that “Matthew collected the oracles in the Hebrew language, and each one interpreted them as best he could.”
- The author of Matthew never claims to have been an eyewitness to events
- Shows knowledge of the destruction of the Temple in Jerusalem in 70CE, putting its writing several decades after the death of Jesus (while yes, this was a “prophesy”, it also says that Jesus would return on “clouds of glory” within the writer’s lifetime and lead his people into heaven…since that didn’t happen, it’s clearly a bit of “revisionist prophesy” on the part of the writer)
- Much of Matthew is cribbed from the other three Gospels, but taking things a step further, accentuating the miracles throughout his life (the first Gospel written, Mark, shows Jesus performing very few miracles)
- Many verifiable names are included in the Gospels, such as John the Baptist, Pontius Pilate, and Caiaphas, but these would be expected to be found in any document of the time." There is a lot more on Quora if you find the answers to this question on there : " Do credible historians agree that the man named Jesus, who the Christian Bible speaks of, walked the earth and was put to death on a cross by Pilate, Roman governor of Judea?". And even more in related questions on there.
