The exodus Moses story has a lot of elements of Egyptian god mythology in it. Moses is told gods name is I am that I am, yet the word were told is the word for "that" is very similar to one of the names of Osiris. Osiris was also born or came from MT Sinai . The Ten Commandments mostly come from the 42 negative confessions of the Osirisian cult. Moses after seeing god has what would seem like two horns or rays of light coming from his head, this could be a reference to the God Amun.
Another thing to note is the ark is very much an Egyptian Bark. A box the Egyptians used to carry around certain gods from one temple to the next during festivals etc.. We will probably never know who wrote this exodus story but it's a pretty god fairy tale of a story as long as you don't take it seriously.
