A entity more advanced named Ra comes to earth 12,000 years ago and builds the pyramids.
Teaches ALL humans how to heal with the pyramids and many other mystical teachings..
The elite push the people out and keep this knowledge for themselves.
They pervert the knowledge for evil, sacrifices etc.
The pharaohs then through bloodlines pass the knowledge down generation to generation.
We have long forgotten but they have not.
These same people / bloodlines secretly continue to rule over us as pharaohs today.
