That’s not true at all. Pretty sure the Aztecs and Olmecs have accurate depictions of the planets in the sky. Ancient South American and North American cultures have oral traditions about visitors from “the sky”.
they used the stars to track the precession of the equinoxes. it was there calendar and navigation tool. Sky gods where from heaven to them, not space.
Do you have any proof of this, or are you just asserting it?
