Antarctica today is covered permanently by thick layers of ice, making it extremely inhospitable to humans. And, unlike the Arctic regions, it had no indigenous population of humans when modern man arrived there. (Presumably because unlike the Arctic regions, getting to Antarctica involves a danger-fraught journey over the open ocean, and once you're there, it's just as hard to get back.) See: Antarctica has no indigenous population
What do we know about possible ancient (or at least not modern) human settlement in Antarctica - perhaps during pockets of time when there was less ice, or people somehow settling in the ice - human extremophiles, as it were? Or, to expand the possibilities somewhat, settlement by some of the pre-human hominids in very ancient times, when there was perhaps less ice? Are there myths and legends suggesting such a possibility? Any archaeological finds that might indicate such a thing? Maybe at least along the coastlines which are not continually buried in ice? Do those exploring Antarctica today concern themselves at all with such a possibility?
We do know that there were periods in Earth's history when Antarctica was not covered by ice and would have been quite habitable, (see Lennart Regebro's citation: A forest grows in Antarctica) so it does have some history of habitability, but that history dates at minimum to 3 million years ago based on that source, long before hominids capable of settling in Antarctica arose. So that period would not be relevant to the discussion. Also see: Antarctica was not always cold, dry and covered in ice sheets..
I have no 'conspiracy theory' agenda here - I am not suggesting, as some 'unorthodox...' (pseudo) researchers have, that there is some hidden secret civilization existing today in Antarctica that is the source of UFO's etc. That is nothing but science fiction IMO. I ask this question simply because it seems rather incredible to me, that although humans had already reached virtually every place on earth in prehistoric times, a whole continent existed that humans never reached. In recent times, we have learned so much about the scope and ingenuity of human life in ancient times and far flung corners of the earth, and so I wonder: Have we perhaps learned something about humans in Antarctica?
Can we say with a degree of certainty (i.e. barring some sudden, spectacular revolutionary discovery) that Antarctica is an entire continent untouched by humans until modern man arrived there in the early 19th century? See: The first documented landing on mainland Antarctica was by the American sealer John Davis in West Antarctica on 7 February 1821,
(I am looking for more than just additional references to the wiki page which I already read - we can all find things in wiki - my hope is that on this site we can delve deeper and further. IMO wiki should not have the final word in all our historical inquiries.)
