It seems likely that he was an actual person. It is not verified, nor is it verifiable. This is the kind of shit Bible apologists like to whip out as if it confirms their beliefs. Almost to a person, people who refer to the Historicity of Jesus Wikipedia page use terms like "verified fact" in the same breath. If you're not intending to be a Bible apologist, you should probably take a different tack.

Nobody (especially the apologist) gives a shit whether some rando Nazarine created a religious movement. They were a dime a dozen. And just because one did, doesn't mean he is the Son of God, or that God even exists. There is literally no useful knowledge to be had in pointing out that Jesus was probably a real person, so the assumption will always be made that if you're hell bent on making sure everybody knows he was so totally super-duper real guys, then you must have an agenda.
