Catherine,

You might also be interested in the Pacific NorthWest tales of Raven.
In some of those, Raven appears both as Trickster and Co-creator.
In one tale raven pulls a shell out of the ocean and humans come out of it.

In another raven steals the sun, moon and stars from the hut of a magical sky being. And when raven escapes all the light falls out of the bag bringing light to all the land.  There is more to these stories but this is a short paraphrase.
Think more than one tribe share stories of raven similar to these.
As far as bringing light there’s a specific Tlingit tale..

“Raven and the Box of Daylight”

There is an article on this and a museum exhibit in National Museum of the American Indian magazine from Winter 2021.
