It is known that Antarctica used to be further north and had a warm climate. there were ancient forests, swamps and jungles, with remains still buried under the thick snow & ice sheet. many Christians have wondered why we haven't found a Garden of Eden, even though the whole earth is mapped out. I say the answer is that it was Antarctica. The splendor that once was is now buried under an icy desert, ensuring that future generations of man could not return, not even now. After the Fall, the Antarctic continent split off from the rest of the land. With Adam and Eve departed to populate the other continents, it drifted down to its present location and was sealed under the ice sheets. the Flood may have played a role in this too, though it's up for speculation. In any case, this knowledge of our origin was lost over time, but it seems like the most plausible theory.
