My Version of the Truth
As many people know, The Anunnaki were believed to be Gods by various Mesopotamian civilizations. Their physical descriptions, personality characteristics, and reason for existence are all heavily debated and each civilization has their own version of who The Anunnaki truly were. There are even disagreements about who The Anunnaki were within each civilization.
It is for these reasons that I feel I can get away with creating my own version of who the Anunnaki were. By using some of the details attributed to them, I have created an alien species, rather than a group of Gods. There are several "facts" that I used to help in their creation. I recommend you read my prologue before reading further, so as to fully absorb what I'm about to lay on you.
The Sumerians did not lump The Annunaki all together as a set of Gods that worked together, but saw them more as individuals, and no depiction of a collection of Anunnaki is known to be in existence.
With this information, I decided that the Anunnaki were never seen with other Anunnaki because those that interacted so heavily with the humans early on were breaking the rules. Other Anunnaki would have steered clear of their meddling peers.
It is said that The Anunnaki "took up dwellings" along side the people Sumer.
With this information, I made it so the Anunnaki lived among the humans after some time on Earth, but did not reveal who they truly were.
Sumerians believed the Anunnaki to be able to "decree the fates of mankind".
Rather than giving the alien species precognitive abilities, I decided that they were simply a much more advanced species with a lot of knowledge and wisdom to bestow upon the humans. This could easily be interpreted as precognition to a simple mind.
In the Akkadian Epic of Gilgamesh, there is a moment where The Anunnaki mourn the destruction of humanity after a major flood.
In my story, the Anunnaki mourn the destruction of humanity after a major astrological event.
Ancient civilizations attributed a wide celestial and underworld cosmology to the Anunnaki.
For my purposes, I decided to use the folly of man to my advantage. The Anunnaki of my story do not have celestial powers, although they do have regenerative powers that heal them quickly and allow them to live for five hundred years. In my series, all the powers given to the Anunnaki by the humans are falsehoods that were used to create dogma out of the alien's existence. This will be better explained in the books. I don't want to give away too much now.
So, yes, The Anunnaki were a mythological species that several civilizations worshiped, but isn't it just like humans to turn anything they can't understand into a religion?
