Greek philosopher did? There were eight people who wrote about Jesus, four of them, The Gospels, are biographies; four others wrote of His teachings from personal experience. (James, Paul, Peter and Jude.) Socrates wrote nothing, in fact, he was against writing; the only record we have of Socrates is the writings of Plato, his pupil. To believe in the existence of Socrates with so little evidence, and not believe in Jesus with at least 8 times as much evidence, or proof, is illogical, irrational. And this from people who demand evidence, reason and logic. BTW, I believe in both.
