Creation Stories!!!

While both creation stories seem very unlikely to me, I think the one in the book of Genesis is more likely. The Navajo story says that people have always been on Earth, and it does not give any sense of beginning or creation of humankind, as the Bible does, by saying God put Adam and Eve on Earth. This is at least an explanation, albeit and unreliable and unlikely one. The Navajo story attributes the fleeing through the sky to lust and envy taking hold, but it does not explain why lust and envy didn't used to be a problem. They existed before but weren't a problem and didn't create violence? The Bible's explanation for feelings such as lust and envy come from Eve eating the forbidden fruit, so again, there is at least a reason for such emotions. Also, the Navajo stopped fleeing the evil worlds corrupted by lust, violence, and envy but they stopped at Earth. For the cycle of the story to continue they should have continued fleeing through the holes in the sky, since lust/violence/envy are very, very present on Earth. I do not understand why they didn't flee from Earth as they fleed from all of the other worlds. The Bible gives an explanation for many things it claims happened, such as people are on Earth because God put them there, and envy and lust exist because someone broke a rule and ruined it for everyone. If the first Navajo man who came to Earth was able to transform things into mountains and animals and hours, why wasn't every other man able to do the same? According to the Bible, all humans are mortal and do not have supernatural powers, which seems more likely to me. While both of these stories are very unfathomable for me, I like the Navajo one more because it is more interesting and pleseant, but I find the Bible creation story more likely, if only marginally.
