Those were the Anunnaki fallen who played your gods and wrote your bible lol. I've gone indepth into it all covering years on GLP. None of it is a mystery and no, many of them haven't left EArth, but they're not physical beings like we are. The hybrid cabal we call the "elite rulers" were their offspring that could walk among men and be used as empty shells for fallen reptilians, greys, and anunnaki to possess as they played their games here. You're waiting for EnLil/Yahweh/Illu/Michael to "save you" yet he is one of the main ones who locked humanity away into a frequency prison we call this matrix.

This book is interesting as there will be a big change next year and many of us have known it for a while already:
