The Hopi nation from the 4 corners region (Utah/Arizona, NM, Colorado) have the legend that they emerged from a cave in the ground and the god told them to spread out.
yes, "a god" in old myths is a keyword that usually refers to a human with advanced scientific knowledge and benevolent intentions, usually... some of them are not benevolent, thus shit like the human sacrifice of the aztecs and the more modern cult of kings
