Is it a coincidence that the last story also consisted of somebody named the Buzzard (Nooee)? In the last story, the Doctor created this the buzzard (Nooee) to be his assistant in creation and here, the Great Buzzard helped to make mountains. I just think it's cool that both stories have this connection.

This reminds me of the Genesis create story, with there only being one being to begin with. Here it is The Doctor of the Earth and in Genesis it is God. These two stories also share the idea that these two people basically created everything.

Interesting how in the Native American creation stories, animals are always seen as helpers and equals to humans, but in this Bible story, the snake leads to Adam and Eve's downfall.
