There's a difference between a guy who is just talked to a few people and a guy who reputedly addressed thousands of people on many occassions and performed divine miracles in front of them.

There were a couple of people around the time who mentioned Socrates in their works, though, and offereed additional views on him as opposed to Plato, who was his student. Xenophon, for instance. The fact that similar accounts of Socrates exist by different authors who weren't in cohoots with each other is evidence enough for his teachings.

I don't believe that there are books by other authors at the time that considered Jesus worth writing about. He gets a mention here and there in the various historical chronicles of the time ("cult leader talked to people, soldiers dispersed mob"), but there's no Life and Times of Jesus Christ, written by a contemporary, other than the what's in Bible, and that can hardly be considered an objective account to his miracles, especially after 2000 years or building an entire religion around him.
