Some Biblical stories are myths, and some are not. As I indicated earlier in this thread, it is at ABOUT the time of King David that we begin reading some REAL history in the Bible. Before King David? Pretty much myth, all right. Sorry, no flood. No Adam and Eve. No Methuselah.

Are you thinking of the Hyksos? They conquered Upper Egypt in the late Bronze Age with their superior technology of war chariots and recurved bows that had twice the range of the simple Egyptian bows of the time. They found the tomb of the Pharaoh of the day, he died from a massive battle ax blow to the head.
