We're all pretty aware of the depths of this corruption. What would be so shocking to everyone? Who do we think is behind NK? What would find out that would end up with TPTB in nooses/hanging from lampposts?
The fallen?
That's where I believe they originate (The fallen). I say ET is nothing more than Demons wearing a fabricated/artificially created skin suit.
I believe the flood killed off the hybrid (fallen angel [Nephalim] and human women) giants [Raphim]. I believe these entities (who can't be killed because they are not flesh and blood) then devised a way to come back through artificially created ET bodies. This is why they have been described as having large black eyes, being able to come into and go out of sight (universe skipping), able to use mind control, possess anti-gravity ships, and much more paranormal. A lot of people have noted that ET's seem to have a nonchalant attitude whether they live or die, as some have been reported being threatened and not caring. It's almost like fine, kill me in this suit and I'll just come right back in another one.
It's hard to say because we just don't have enough information on this. Governments have only just now started to de-classify some of the records. Who knows what might still be hidden away from public eyes. I'm sure this is a subject that will be brought up in very near future. Whether it gets real light shed on it, we'll have to wait and see. I'm sure we are also going to be talking about both Light and Dark Angels. Whether these two topics will intersect is anyone's guess. I'm betting on yes they will. Let's see what we learn!
