Just leaping in here for a quick comment.
The Aborogines of Australia have a story that the Seven Sisters of the Plaeides were seven humanoid ET women stranded on earth after a battle with Reptilian ETs from Orion.
The Reps had agreed to hand over control of Earth to the forces of Light but reneged and attacked instead.
The seven women, with te remnants of their advanced techology hybridized their DNA with a local hominid (almost a million years ago) and after the second attempt succeeded.
To them Orion represents the Hunter Reps who were and are trying to exterminate the human race.
There's a site in Australia where this battle is supposed to have taken place-Kariong, which does have Egyptian heiroglyphs etc.
This is based on a book by Valerie Barrow, called Alcheringa.
She has a site [link to www.youtube.com]
My only qualm with her and her message is that it was endorsed by the late Sai Baba, who seems to have a deservedly bad reputation.
