Short of inventing a "time machine", and going to meet him yourself, no you won't.
Call it a "double-standard", if you like, but Socrates has not apparently been claimed to be THE God, a God, a Demigod, or even mildly super-human.
Now, when you compare that against claims of a miracle worker who did "amazing", yet irreproducible deeds, against a plain man, the possibility of a plain man existing who thought those thoughts seems more plausible (after all, the thoughts had to come from somewhere) is more credible than the possibility that:
God Almighty, Creater of "ALL" (or whatevr) made a woman pregnant by virgin birth, so he could walk around and stir up trouble, do the odd miracle for credibility, then commit elaborate suicide to "save everybody".
Or make it possible for everybody to be saved.
Or get ready to come back "any day now" for 2000 years to make "his kingdom".
Or go to the Americas and become a savior there, too.
Or crawl out from under his rock every so often and check for a shadow.
Or appear as a 50 foot apparitions to televangelists to ask for cash.
Socrates isn't even spotted on tortillas and rust stains. You'd think his face would pop up occasionally, too. Elvis does, all the time.
Socrates hasn't been claimed to have "come back to life".
In short, Jesus sounds like a UFO tale.
Socrates sounds like just another clever guy from Greece.
You want to make the claim that some guy said the kinds of things Jesus said, I would agree. Good enough. Somebody said it. Call him "Jesus" if you like. We may never know the true authorship, and one name is as good as any.
We only need routine evidence to accept that a typical human probably existed.
You want to make *AMAZING* claims about a SUPER HUMAN, you'd better have *AMAZING* and SUPER HUMAN evidence.
Is that simple enough?
