Greek or Norse Mythology?

The Greek and Norse gods were also associated with the powers of nature. Similarities in mythologies have a lot  to do with the thought processes of humans that invented them and how they use those processes to answer questions such as how does the Sun move across the sky, and that alone presents such a limited number of options and possibilities that the chances of separate populations arriving at the same solution (a Sun god - Sol, Sunna, Helios, Apollo, Awondo, Ra, Sekmet, Bast, Aten, Tonatiuh,  Ri Gong Ri Guang Pu Sa, Tai Yang Shen, Surya, Amaterasu) is quite high. The same is true of creation myths, and here it is the differences between the various mythologies are just as informative - The Norse gods created the Universe whereas the Greek gods were created by the Universe - here two possible options and they picked different solutions.

 

Regardless of when homo sapiens migrated into the Americas (30,000 or 14,000 years ago) they were the same as us in every physical way, with the same brain capacity and the same speech abilities for memory and story-telling, it is possible that the mythologies migrated out of Africa with them.

When you live in tribes, with a flat structure, You will have mostly Gods of nature.

Moon, Sun, River, Thunder, Old Tree, Ocean, Mountain.

 

When you move into a more complex city based systemj (like the times of the known Norse & Greek myth) 

You still have nature gods, but more complex gods are added, God of Trade, God of poetry, Gods of War, God of justice, ect.

 

 

Might also be 2 diffrent clans with diffrent religions melting together.
