Dont you think the torah has been changed by man up to a certain extent ,,through manipulations over time ?

Man wrote the torah, the bible, and everything else in the world. If I told everyone that God came to me in a dream I would be locked up, but back in those times, saying things like that did work. In the words of Lewis Black (also a jew) "I have thoughs, and that can really **** up the faith thing".
