yes genesis 1..right.
stories past down from one sandle wearer to another with all of the inaccuracies of word of mouth and finally written on goat parchment for all to enjoy.
sure.
you have no reason (but circular reasoning) to believe that it was passed about by word of mouth, in fact it was not. Yet even so, in other cultures, oral histories are the normal mode of communicating past events and those that carry the histories are quite proficient at accurately retelling the story, unlike our own culture.
