Neither we contemporaries, so relying on
at least second hand information. Considering the time they lived in, they likely heard it orally, rather than read about it, and stories rarely survive without alteration when passed in verbally, especially when claims of divinity are involved. In each case only minor mentions are made, which is odd considering that when Jesus died supposedly
zombies got up out of their graves and went into town and were supposedly seen by many people. Seeing the dead rise would deserve more than a tiny mention decades later, wouldn't it? Even in the time before major new outlets word would get around of
zombies.
There is no contemporary ex-biblical evidence for Jesus. Then consider the bible, Since no amount of anonymous textual claims of supernatural powers are sufficient to believe them what are you left with when you disregard them in relation to Jesus? When you remove from consideration all bible stories relating to claims of supernatural powers you end up with someone who was just a vaguely vocal rabbi.
Then you can draw analogies to Socraties. He may not have existed and his wisdom and teachings just the lumping together of other people's ideas. Or perhaps there was someone upon which the historical person is based and over time other people's ideas have been credited to him (success breeds success, a phenomenon seen in
the academic community).
