Maybe not so obvious to me, because I'm not exactly sure what you mean. Maybe you mean what I think you mean? That's to say that Jesus, the man, is absolutely dwarfed by Jesus, the legend. Parsing through what we can KNOW about him historiographically is a profoundly daunting exercise since there are no extant records contemporary to his life (as you allude to) and that all of the earliest surviving records have inexorable theological bias. On the other hand, there is quite the temptation on the part of skeptics, especially anti-theists, to go all the way, so to speak, with their debunking exercises- aiming to leave absolutely nothing in the Christian apologetic's hand.
