Do some beleive that the ancient Egyptians and Mayans knew that humans came from another planet or galaxy?

I know that the Shawnee Natives Americans say that the word "Shawnee" means people from the sky. If they had this thought then it is possible that other native Americans thought this. The Aztec have a story of a blonde god. Maybe related or maybe not, Hitler got his idea of blonde superior people from a New Age mystical group which claimed that blonde people are descended from the people of Atlantis.
