“But it is a close to scientific certainty now that humans got to southern Chile roughly 30,000 years ago, and various places in between, and that they got here via the Pacific coast route.”
I have studied this in depth for years now. And there is absolutely no reason why a southern route wasn’t just as possible.
The Mercator projection completely skews our perspective and even the experts are subconsciously fooled by it. And this is why we refuse to accept it. Visually the distance looks impossible by the Mercator projection. But in reality it isn’t far at all from Australia to Tierra del Fuego. The currents favor it, the winds favor it, and there is food and water all along the ice packs of Antarctica. If the inuit can live on ice now so could early man then. If man could float down the coast from the north then they could float across in the south. It could have even happened simultaneously or a southern migration before. There is some real explaining to be done why the oldest sites found are in Tierra del Fuego and not in the north.
You just may be right.
But you're surely bucking the "narrative."
From what I see, the narrative is just another word for "That's my story, and I'm sticking to it!"
Just remember, "trust the science" except when it's not the truth, which may be a frequently occurring phenomenon.
Now if you contend that ancient extra-terrestrial aliens took them that far ...
The DNA doesn’t support it, and there was no reason for Australasians to go anywhere, anyway: plenty of land and a very small population. They didn’t even make it to New Zealand.
