The Anunnaki that came to now known as earth were the Pharoahs.
They centralized what is now known as Africa, they were called the Ishtars, that's were Isis comes from.
The Pharoahs were hu-manoid, they were descendants from the Ishtars. A group of Ishtars came to now known as earth, they split into two groups. One group stayed in Africa, and the other group went to now known as Iraq, the middle east.
Being in earths atmosphere their DNA mutated and their appearance started to change.
Which also changed the amount of energy they carried in their field, becoming positive beings.
They eventually became the Kushites, and the other subdivided group became the Black Moors.
The Kushites were a peaceful race and the Black Moors were Warlike.
The Ishtars created the Nephilim (demonic) by using their own Life energy and going to a different time line to get hu-manoid DNA from their descendants.
The original timeline for Dragons, Serpents, Ishtars (Annunaki) were demonic.
