Early creation stories

While both the Navajo creation story and the story of the beginning of human kind in the book of Genesis are unlikely to have happened scientifically speaking, I believe that the version in the book of Genesis is more true then the other. I just feel that even though neither story is exactly realistic the one in the book of Genesis is much less far fetched then that of the Navajo creation story. The Navajo one speaks of one man basically creating earth and everything that is within it including seasons, animals, and time. This is an extremely different idea then that in the book of Genesis which believes that God is the one who created earth and Adam and Eve. Even though the idea of god might not be exactly a scientific concept, my religion and beliefs tell me that this is what truly did happen.
