For the question on where do the Trinity of Enki, Enlil and An come from. That’s multiple places. Enki comes from a star system I suspect to be Alpha Draconis, Enlil I take to be of Pleiadean descent, but that’s speculation.
An is apparently a very high ranking being from perhaps the original pure-blooded aquatic ape lineage of the Jehovah Anunnaki. But these origins (Djinn from Orion) are really superficial, because all species and races have good guys and not-so good-guys in them.
What they do today is what defines them in terms of what we are up against. The way things shook out in the religion program is Enki played satan (his last name is Satain, so go figure), he also played the underdog, sun of god in many dramas.
His brother from another mother, but same dad was Enlil who played god the father or YHWH, and An who apparently fathered them both (through rape I am sure) plays out as the holy spirit. These are celestial and aetheric terms.
In the more down-to-Urth application of religion, it was Enki who represented the holy spirit when it comes to playing the role of Mother Mary, all explained in the handbooks, as it was he and his sons who were androgynous and could pose as either male or female.
The role his son Thoth played was so vast and huge in our history books it is difficult to even begin covering it. He was Pan, SET, Adam (Atom), various female gods, the original hermaphrodite Hermes the father of alchemy, mathematics and medicine, father of Cain, who killed his brother Abel, the original “King” (the Khans of old), Serpent King, Quetzalcoatl, Janus and came back life after life after life as someone else who always played a major role in a different body.
The history is awfully elaborate because the game has been going on for 1/4 of a million years just with these new contemporary players that came hundreds of millions of years after the Anu Elohim started this fight with the fallen angelics.
So parsing through who is who is intensely complicated. You really should look into the human handbook series, as the identity of who Mother Mary was, who Jesus was, Poseidon, Zeus, Apollo, Adam, Eve, Lilith etc. are shown and some of the ancient history finally explained.
It is unbelievable how contorted all of that drama became after being translated through thousands of dialects through many thousands of years.
I know some of the beings who were there in the garden of E-Den 252,000 years ago and can tell you that nothing you’ve ever heard about any of it was actually correct, even remotely.
