There was once a mythical coyote during a time of monsters, and immortality.
The coyote was a trickster and a faker, but wanted to be a warrior.
The coyote was able to kill off a few monsters but sometimes a person would die in the process.
However since they could get revived it didn't matter to anyone.
The coyote was known to be ugly which is why he would change his face to get the girl he liked.
After living for so long, he had done everything he ever wanted to.
This was when the Earth chief finally took him off of the Earth because he had done everything he needed to do.
The point to the story was that living forever isn't as good as it sounds. Eventually you'll do everything that you wanted to do and your life won't have purpose anymore (the chief taking him out for doing everything he needed to do was a metaphor for how we eventually die and get taken out of this world).
