There are some major differences in the Babylonian Epic of Creation and Genesis. Enuma elish has more of a story aspect to it since there are so many characters involved. There are multiple gods in this story. There is also an evil villain, Tiamut, who is killed and the remains of Tiamut are turned into the sky and sea. This is a similarity to Genesis since in Genesis the sky and the sea are one thing split into two. Genesis is a much easier story to follow since there is really only one character, God. It makes sense to me why more people are familiar with Genesis than with the Babylonian Epic of Creation since Genesis makes more sense and is easier to understand.
