Personally I believe that the biblical stories are true and that the pagan myths and legands that are similar are counterfeits created to discredit these events.
The pagans who "invented" the Sargon story lived a thousand years before Moses?
Were the pagans more prescient than the Jews, or modern Christians?
Passover rarely even falls at the same time because it's based on the 15th day of the Jewish calender month of Nissan.
