&gt;There’s more evidence for the existence of Jesus than any other ancient figure

BS.  We can debate the existence of Jesus, whereas no one doubts the existence of Plato, Socrates, Aristotle, Cleopatra, Julius Caesar, Alexander the great, Confucius, countless Chinese emperors and Egyptian pharaohs, etc.

So honestly kind of a side note because it's only about one of the names you mentioned, but there actually has been a fair amount of debate about whether Socrates was real or just an invention of Plato and some of his peers. Basically the argument is because Socrates never wrote anything himself and everything we know about his beliefs was written by other philosophers.
