I wouldn't say all predynastic stories are false. There is truth in them, same goes for holy scriptures. Much knowledge has been lost to wars, movement of the peoples, etc. To me, one of the major culprits being translations. Much gets lost during translation be it by limits of a given language/culture and/or the interests of the governing body and/or translator/s.
