Great choice; super awesome music. Spock agrees.
That said, I'd like to say a few things that might address some of the reluctance to consider the real meaning these strange pictures. (which ARE evidence of "something unknown" at the very least) (And this whole topic is indeed very problematic, I admit.)
One is the term "Mudflood". A lot of people don't like that one. Widespread localized quasi-geocalamity of unknown breadth and time period? There is no point in arguing over terms. The point is: what the hell are we looking at? What the hell happened?
A second point is regarding the term Tartaria. While this was clearly a place seen on maps and talked about in encyclopedias of the past, it has also been idealized and expanded to mean all sorts of things that are likely not true. An association is made between a golden era, and certain architectural styles and the name Tartaria. The application of the term Tartaria may just be misdirection. But what's in a name? Call it whatever you want. The point is all the buildings that span the globe which have a homogenous flavor and could be said to represent a worldwide culture or empire of a more unified humanity.
Yes, this beckons to a longing for Camelot; a better more heroic time of greater honor and righteousness. And that can sucker us into believing all sorts of things we hope for in the future as well as the past. But calling it all Tartaria, to me, is like a piece of disinformation that discredits the actual evidence on the ground and in the old photos. Same thing applies to all the flat-earthers who are touting the Tartaria meme. Their flat earthiness makes the Tartaria meme look even worse.
So, remove the monikers and prejudices and just look. It is amazing. We all know and were taught one civilization was built upon the ruins of another. But to see this in pictures of the "new world" (eg, both USA and Australia) kind of makes a buffoon of the historical narrative we have been given.
One last question and answer: Why is this such a hot button topic? What could the controllers be most anxious to conceal: That they are the controllers! That we are an experiment! Earth is a giant Petrie dish of souls and they are intentionally jacking us around. No! go back to sleep! As Holden Caulfield said, "Sleep tight, ya morons!" ) I am not directing that at you but I think that is the point of view of the PTB.
It is obvious that the WEF, WHO, WOKE and Agenda 2030 are a flat out assault on humanity and they are trying to assume control and dictate terms of our future existence. There are plenty of threads on that here on Cass.
But this is not anything new. What goes around comes around. And that is what I think this "mudflood/tartaria" thing is about. (and of course I am on the skinny branches here; I know that) It seems to have happened in the past 400 years approx. So, I have high hopes for the Worlds Fairs questions. That is a foot in the door for some confirmation one way or the other on some of these ideas. The flood gates will open (punny) or the door will slam shut.
Overt time line manipulation not that long ago? A confluence of geo-physical and cosmic solar cycles presenting an opportunity? IDK. A reconfiguring of humanity? IDK
But if one realizes time line manipulation is ongoing, it changes the focus big time.
