By "Moses story" I assume you mean that he existed? Yes. I'm not sure if I believe all the Bibles says about Moses, and it doesn't really matter to me. A lot of the old testement means little to me. A lot of the stories about different people and events through out the whole Bible mean little to me, except Jesus' teachings. None of it really gets me any closer to God, except Jesus' teachings, and that's my only goal in reading the Bible, or any book.
