Here I will present my newest theory connecting Antarctica/Ice Wall, Atlantis and how it all tied in to flat earth. First of all there are already many theories stating that the continent of Antarctica (spherical model) is a former ancient continent of Atlantis, that perhaps shifted far south to the polar region during the ancient doomsday that consumed the planet many thousands of years ago. The first person in the western world to describe Atlantis was of course Plato. In his writings Plato stated that Atlantis was a circular continent larger then Asia. Now if we look at the map of Antarctica on a globe, it appears to be kind of circular but it certainly not larger then Asia. However on a flat earth model this makes perfect sense, because on a flat earth Antarctica is larger then any continent, and it completely surrounds the world, creating a giant circle of ice.
So can it be that once upon a time, long before the disaster there was no ice wall, rather there was Atlantis, a huge landmass of the south. I think its very possible. Given that the earth could be an infinite plain, Atlantis could have stretched for millions of miles.
