Well, aside from conjecture, there are lakes under the ice sheet that might contain unique life that would be worth discovering and studying.
The outline of the continent that we see in a classic Antarctica map is actually the boundary of the ice sheet, not the underlying continent. That is very interesting and could hold answers to many geological questions, including continental drift and the history of Pangea.
Getting more into conjecture, there is the possibility of a Nazi fortress, or the entrance to another realm. There are historical facts that could bolster some of this such as the reports of Admiral Byrd and Operation Highjump / Operation Deepfreeze, both of which are highly researchable.
Highly possible is the prospect of the site of a lost civilization. I believe human history goes back much further than we are led to believe, by tens of thousands of years, constantly wiped away by cataclysm. This is evident in the impossible structures and monoliths that we find here today, and the probability of finding a Gobekli Tempi or a Teotihuacan or a Puma Punku is very great.
Looking at Biblical / mythical information, it could be the enterance to either the Underworld, the Garden of Eden (Shangri-la, Agartha, Shamballa, Vahalla, etc.) or possibly both.
I do believe we are being decieved of the true nature of our world. The flat earthers are most likely a psyop to mislead us with disinformation, but the idea of a realm is closer to the reality of earth than a planet spinning in outer space.
On the topic of the ayy lmaos, I believe they are a misnomer. The idea of "aliens from outer space" is manufactured to get us to accept foreign entities, when what is being described as an "alien" is actually native to our world, living in a different zone or on a different frequency.
