The Sun God and Moon Goddess, both worshipped by the ancient Inca, had a son and a daughter who were sent to earth and became the first Incas and progenitors of the race.
Inti – the Sun God – and his wife Mama Quilla – the Moon Goddess – taught their son, Manco Capac, and daughter, Mama Ocllo, the arts of civilization, which they then shared with the Inca people.
As brother and sister, we’re confronted with the same incest issues that arise in Christianity – with whom did the offspring of Adam and Eve mate? – as well as other mythologies.
There’s the paradox of incestuous gods and the practice of incest forbidden among the human population. Perhaps incest is one of those things reserved for deities because of their perfection, but forbidden to humans because of the disastrous consequences of inbreeding – just look at the European monarchies. As with so many things, such as the wholesale destruction of human life, it’s acceptable for the gods, but not for the rest of us.
How could such similar stories be so widely distributed over space and time? After we account for the localized variations, the basic facts are almost identical. I find it highly unlikely that these stories spread from earlier cultures around the world through personal contact after the development of civilization.
Possibly, the stories are literally true and were carried around the world by the first humans to leave Africa 60,000 years ago, but that’s a very long time for these stories to persist, even in a distorted form.
Is it possible that beings with highly advanced intelligence have visited multiple groups over the millenia and given them the knowledge of civilization? If we believe even a fraction of the stories, this is the most plausible answer.
Whether we call them Gods or extra-terrestrials, they clearly came from somewhere else – most have some direct connection to the heavens – and shared knowledge and wisdom with our primitive human ancestors.
