i see them as a subspecies of human, from the same root, whose different constitution allowed them to become spiritually advanced

they clearly had some kind of "flying chariot" technology as well as being able to project themselves into people's minds and communicate by what could only be described as telepathy

you have to keep in mind that the other humans, who are like us, were not a lot different to the modern example of the isolated polynesian tribes who were visited by an american army pilot who crashed on their island, and the way they recorded the story was greatly amplified and primitive in that they saw what to them was miracles, these weapons that shot "lightning bolts" and "spinning flaming swords" (which were probably also some kind of energy weapon)

and we all have the genetics of these angels in our family lines dating way back to the time of Noah, 10,000 years ago, indeed according to Enoch that was part of the problem that led quickly to the sodom and gomorrah and tower of babel situation which i strongly suspect dates to 6000 years ago, as there is a global disaster every 6000 years, but it's every second one that is bad, like Noah, and the other one is more mild, like what happened to Sodom and Gomorrah - impactors from space formed from a solar superflare that ejected a massive amount of material that condensed and smashed into many places across the planet, there are stories of these, sometimes described as "great fiery dragons" in norse mythology, for example, and the likely cause of the desertification of north africa and the middle east

and i also think that minimizing the amount of "authorized" bible texts that contained more detail about the interbreeding of angels and humans was part of the agenda of the Council of Niceae (sp?) because they wanted to suppress what was at the time common knowledge, and purged Enoch from most of western and central europe, but the text survived not just in eastern europe, but also in ethiopia and in israel as well (all three religions/denominations accept Enoch as canon) but this wasn't available to those central/western europeans between the formation of the catholic church and the discovery of the Ethiopian Orthodox text, and more recently extensive fragments of Enoch were found in the collection of documents found called the Dead Sea Scrolls

i think that the evil ones have tried to hide the facts from people and promote instead this idea of disincarnate beings and muddled the translations to obscure this - even the official canon books in more modern translations have many hints and references to this that were curated out of the versions we are more familiar with.

this is my rational, scientific view based on history and psychology, and the documents themselves, and that if the texts say that they were going to come back before the next disaster, they are about due to appear and fulfill their promise to end the rule of Satan and his cult of death and decadence, very soon.
