While it is true that antarctica was indeed lush at one time, that was on a geological scale. You are talking about hundreds of millions of years ago as opposed to the hundreds of thousands of years of humans. Antarctica has been ice covered longer than any evolutionary evidence of even proto-humans nevermind homo sapiens sapiens.
Genesis 1:1 IN the beginning God created the heaven and the earth.
2. And the earth was (should be "became") without form, and void; and darkness was upon the face of the deep.
And the Spirit of God moved upon the face of the waters.
We are not told when the earth became without form.
"Antarctica has been ice covered longer than any evolutionary evidence of even proto-humans nevermind homo sapiens sapiens."
There is no proof for you supposition. The Piri Reis map and others published by Charles Hapgood are good indicators that it was Ice-free in ancient times.
It can possibly be considered Ancient Atlantis since Atlantis sunk under the water and Anartica is buried under frozen water.
More importantly, the dispersal of "Atl" in both America and Europe seeks a common origin.
