What if the reason for the trips from the elite, to Antarctica, is due to they have found the Watcher (or are looking for the Watcher) that Enoch says that GOD sent Raphael to bind and bury,(the Watcher Azazel) in a desert until judgement day where Azazel shall be cast into fire.
Despite its thick ice, Antarctica is classified as a desert because so little moisture falls from the sky (from this website- https://www.livescience.com/21677-antarctica-facts.html)
If 'they' have found the Watcher, this could explain the technology boom that we have had over the last 100 yrs or so. When the Watchers married the women, in Noah's day, they taught them all sorts of things. They taught the women to wear makeup, they taught them to make weapons of war, and many other things.
What if 'they' are getting our technology from the Watcher, if they have found him in Antarctica?
This would also go with the Bible Verse, where Jesus says ' But as the days of Noah were, so also will the coming of the Son of Man be.'
In the days of Noah, the Watchers produced children with the daughters of men, and the bore giants. If 'they' have found the Watcher who was bound in the desert, and 'they' decide to allow him to produce offspring (or if he breaks free), this would make it 'as in the days of Noah'.
They may already have produced children with this Watcher. This would explain the depravity of the elite. This would explain most of the evil that they partake in. The children of the Watchers (Giants) resorted to eating human flesh in the days of Noah, due to the People couldn't produce enough food to feed them. If they developed a 'taste' for human flesh, this would explain why they sacrifice, eat, and drink the blood of humans in our times.
