I am intrigued by this investigation and years ago read the books by Sitchin on Niburu and the Annunaki. But the scientific proof from archaeology is uncertain because we do not fully understand various local contexts in which artifacts are found , such as modern technology from earth strata millions of years old ( batteries and such). Such findings are simply ignored simply because there is no context in which they can be understood, except for theories such as cosmically based intervention.
We may have some very strange relatives indeed.But chances are that we will never know with certainty and so religions will continue to be born around the issue. But I do love to read about it.Thanks for the ping!
