Did some carpenter dude called Jesus exist? Sure, I once had a dude called Jesus install some cabinets at my home. Did the religious character described in (among other works of fiction) the Bible exist? No he did not, or at least he existed as much as other historical fiction characters.
It’s very hard if not impossible to figure out if stuff written down thousands of years ago was fact or fiction. Even persons that seem to be reliable sources from that time have had works of fiction or embellishments mixed in. Almost all we know about thousands of years ago is because people wrote shit down and the amount that actually survived is very little.
The sources you claim are from well past the time Jesus was alive, so it’s questionable how reliable sources they are. I also would not trust anything written down by cult followers about the cult leader, this is basic common sense.
And if you’re going to link Wikipedia, you can at least read the article instead of just the blerb.

I did read it. I chose to ignore the evidence written in the Bible of his existence and went to the writings of Flavius Josephus and Tacitus. And it wasn’t a very long time past his death. Both less than a hundred years. Did you read it?
And with the same logical of not having physical historical evidence, then Diogenes of Synope didn’t exist either
