If you go past 12,900 years ago...oceans were around 300 feet less than what they are now. When the glacier over North America melted (in a hurry), it had dramatic affects on coastal regions...raising up the water levels.
A couple of years ago, I was reading through a piece on maps, and there’s this map which has been around for generations...showing coast regions of Antarctica. It’s a port to port map...meaning you used it for sailing from one port to another. It begs questions because it shows the bays and harbors along Antarctica region. But you’d have to go back a heck of a long time ago, when this region not have been covered with ice or glaciers.
I have seen those maps, obviously ancient knowledge passed down. But I have always wondered why not a migration along the Antarctic ice sheet? If the Inuits could do it in the north and survive just fine on what few resources are available in the north, why not the same in the south? Because we can’t find any paleo-shipyards? no wood for boats? The Inuit don’t have these either and can float, hunt, and survive just fine.
And to add to your point about sea levels, the Antarctic ice sheet would have been much larger and well within reach of New Zealand. And if they could not float, then how did they get to Australia 60,000 years ago? Even with lower sea levels they still had to float to get there. So they could float to get to New Zealand and then forgot how? It is not unreasonable at all to think that if man reached Australia and New Zealand 60,000 years ago that they could have reached South America by 30,000 years ago. The Antarctic Circumpolar Current would have taken them right to the tip of South America even if it was by accident.

Had humans been on an evolutionary track that had started 13,000 years earlier, Al Gore would have been trying to stop this.
