This issue is still relevant after the Anunnaki departed our planet due to the nuclear destruction of Sumer, and the birth of Babylon. What would happen if they came back?
Sitchin says in ‘The End of Days’ that they will undoubtedly return, and he bases his argument on the circularity of periods. In this sense, the Anunnaki are expected to return at dawn of a new age.
Our forefathers came into contact with another race, whose members pointed to the sky when they were asked about their origins. It’s reasonable to assume that they originated from a world comparable to ours, wherever they came from.
It seems reasonable to suppose that other alien cultures would perform the same things as us to locate other planets comparable to ours. If we find out that Gods may be extraterrestrials on a distant planet with similar interests as ours, then we might wonder what we would do in their shoes.
