Wrong, It is a land mass, it is the 5th largest continent, it even has mountain ranges, it is mostly desert.....but here is the rub it is mostly covered with snow and ice and unlivable for civilization. I think it was shortly after the airplane was invented and developed that someone flew beyond the coastal edges and discovered those edges were more then just ice bergs or islands. If you get some old maps or globes earlier then about 1910 you see where they show the area as the Antarctica Ocean, because they didn't know what was beyound the edges, and assumed it was water.
