50,000 starpeople came on a mission to bring the Light of the Source of All Creation to this, our corner of the galaxy. Very few survived the catastrophe to form an establishment on the Earth. The light was needed for the Earth was shaded with darkness due the activities of the Annunaki, a race insufficiently evolved to be beings infused with the light of the Source of All Creation.
The up-standing hairy-ape creature – among other genetic experiments – were created and developed into a cave-man like race of beings that followed orders and worked as gold miners for the Annunaki. The Annunaki wanted to have unlimited potentialities but were insufficiently evolved as a race to connect with the Source of All Creation; they offered their creations (as sacrifices) in order to receive higher essences. There was flouting of the order of Hierarchy – from the Angelic Realms.
