re: That's what I thought...
I do not know if all Mormons on creationists, but I do know one of their main beliefs is that you can "progress" to different higher levels after you die until the point that you can become the god of your own universe.
Of course they have nothing on the Christian "Scientists" when it comes to outlandish beliefs: All humans are possessed by the souls of aliens who came here due to an evil galactic overlord 75 million years ago.
