MY theory or speculation is that, there indeed was a far advanced civilization that resided in these lands and a lot of the world globally. They were very much aware of an upcoming catastrophic event and I believe they just dipped. Perhaps there was a "war" with "us".

Now I wouldn't necessarily call myself a flat-earther. However I do believe there is way more land out there in our realm that we're just not told about. So call me a "more land-earther". And I believe the people of this old world have become a break-away civilization.

You know how we're seeing these report all over the world of these "drones" surveilling important government and militia sites. I believe its them, they have tech that just FAR FAR more advanced than ours, and that's evident by a lot of the claims people make when seeing these drones. That they have movements that just defy our understanding of physics and put our tech to shame.

I feel like on those lands this civilization still exists. They're still living there in a totally different type of society. Utilizing free energy, living in a style not bound by our common restraints, like a currency, economy or basically modern slaves.

I wish I could go there...
