Sorry i'm not sure what FET stands for. (is it flat earth theory?) i'm new to this.
Regardless allow me to clarify what i meant.
Scientific community believes that during the cretaceous period (and before) parts of antarctic were covered by a tropic like forests
"The continent as a whole was much warmer and more humid than it currently is today," says Gulbranson, a professor at University of Wisconsin – Milwaukee.
The landscape would have been densely forested with a low-diversity network of resilient plants that could withstand polar extremes,
like the boreal forest in present-day Siberia."
got that quote from:
https://news.nationalgeographic.com/2017/11/ancient-fossil-forest-found-antarctica-gondwana-spd/To my understanding that was during the Gondwana period (roughly 180M years ago) when all the continents were one.
Later slitting up in the Jurassic and Cretaceous periods. Making modern day Antarctic and other continents.
So during those periods the wall couldn't have existed in antarctic since it wasn't where it is now (in terms of location)
So to reiterate: you're not wrong in saying FET "contends" that Antarctic
is the ice wall, i'm just saying back then it could not have been so. (again assuming that the scientists are right) and it became a part of it sometime during or after the ice age.
