That was intriguing. Much seems plausible and just as much seems too out there. I did wonder, just as one of the twitter commenters, why the alien being talked German to the admiral. Another commenter mentioned a theory that Antarctica could be Atlantis, where it didn't sink to the bottom of AN ocean, but to the 'bottom of THE oceans'. Inasmuch as I believe in underground caverns, I don't think the earth is 'hollow' (or flat, per the questionable NASA airplane document). The bible does make it sound like the arks of Covenant/Gabriel (which I never heard of) were weapons. Isn't that what brought down the walls of Jericho? I believe the continent wasn't always frozen. The pyramids there, manmade or otherwise, aren't too surprising as they've been found on all continents. It does give a bit of creedence to the theory that they were energy providers. If there are otherworldly beings of any sort down there, I question their benevolence since they seem to hang with the scum of our Earth. A question that could be answered by the reference to the leader as 'Master'. Doesn't sound like anything I'd want to meet. I've always said, though, should Antarctica ever melt, archaeologists, anthropologists, among many others, would wet themselves.
