I was studying the Egyptian Book of the Dead the other day and found it interesting how they believed when a man died the God Anubis would weigh their heart and judge them, if they lived a good life they would be taken to the God Osiris and granted eternal life, while if they didn't live a good life, their souls would be eaten by the great destroyer Anak (the monster who was part lion, hippo, and crocodile) and they would cease to exist.
I think there are many similarities between the Egyptian religion and that of Christianity.
