you'll find several kinda identical storys through the whole history of humanity
"gods" ascended from the heavens and brought knowledge and technology
these gods established religion based control systems with worship, mined and farmed resources
these so-called "gods" were fallen angels which you can find more information in the book of Enoch
they also created some hybrid race the Nephilim - giants which were the reason for the flood because the world had been so much corrupted and wronged in so many directions
they disembodied spirits of the giants roam the earth and are known as evil spirits and serve the kingdom of darkness
they act in a hivemind and manipulate humanity on a larger scale behind the scenes in the minds of people. its literally mind control but were talking about something like a spiritual possession without even noticing it because they hide so damn well in your own mind.
they are trying to unite the world under one religion, worship system to declare their leader the first rebel as god
the devil is trying to get as many people with him to hell as he can do
we have been born into a fight of your soul and how you spend eternity
