There were several Sherlock Holmes-like people, police detectives, doctors and so forth in Victorian days who were the basis for the Conan Doyle character. They were actual people and we have records of them and what they did. None of that means that there was a real guy named Sherlock Holmes running around London solving mysteries. There would be newspaper articles, family information and so forth about him. And there is not, because he was fictional, not real.
That is what it sounds like with the "Jesus really existed" stuff. He sounds fictional, not real, even before you add in the magical stuff. There certainly could have been several itinerant Jewish preachers roaming around the Middle East during the Roman Empire. Some of them probably gathered groups of followers and made public speeches--why not? Someone might even have said the "love one another" stuff and annoying parables that are attributed to "Jesus". One of them might even have pissed off the authorities enough to get himself executed. I don't think anyone would dispute that this could be factual.
But there is no evidence from the time period that there was this one guy who did all of these things-- plus did miracles in front of hundreds of people and came back from the dead
. Those are things that would get noticed by lots of writers and observers in any time period. You would think that someone would have passed on the info about Jesus along with the shipment of spices and silk. However, he is not recorded in the Jewish records of the time. Nobody in India or China or Egypt or Ethiopia or Rome heard anything about him, although these people had been traveling and trading goods back and forth for centuries.
And although people wrote about all kinds of things that we still have records of, including everyday gossip, news from home, tax bills and shopping lists, nobody anywhere appeared to notice the one and only son of god, the true Messiah, showing up, healing the sick, raising the dead, getting killed and coming back again.
Wonder why that is.
