The Earth on Turtle's Back

This story, to me, seems like its another non scientific way to explain how earth was created. The Great Tree represents earth before it formation. All the men that tried to uproot the tree represents all the time it took for earth to form, and when the chief finally uproots the tree earths formation is complete. Now that earth is formed, life starts to up rise. Each animal who tries to bring the earth up to the surface of the water represents early life forms. Each time a different animal try's to get the earth that animal goes deeper than the past animal. When the animals go deeper that represents evolution. The animals get stronger and better instincts the further into evolution they get. The muskrat may not have been the strongest, but its instincts for survival have increased because it knew that the Sky Woman (could be its family or companion) needed the earth to survive. The turtle represented the world changing into something with life, and flourishing as a planet. Now the earth was completely evolved and life could flourish on land as well as the water.
