My first thought was that there is plenty written down about him. It tells the story of his life. You can find out that way. But I see you are asking if Jesus is a man or God.
I think of him as a pretty good politician and organizer. He represented an underdog, and he employed unorthodox methods in his political campaigns. He had such a remarkable story (or people turned it into a remarkable story), that his story inspired millions, maybe billions of people over time. It inspired the development of the longest-lasting organization on the planet.
I’d say he was perhaps the most successful person in history, although he did not live to see his success. His martyrdom has been used more effectively than any other martyrdom in history. There is much in what he was purported to say that is valuable, and some that is not so much so. In any case, the historical accounts are unreliable. Most are.
I don’t know if he was a wise man. I’m pretty sure that a lot that is claimed on his behalf wasn’t really done by him. I’m certain that he is no more the son of God than anyone else is. I think he was a pretty good guy (I’m always on the side of the underdog), but I’m not the people who deified him were so good.
