North American continent was wide open and practically empty ... they are all extinct now probably due to hunting pressure.

Empty? there were millions and millions of animals and gigantic flocks of birds; many inhabited sites lend the human population may have been in the millions.

Glaciers only covered the top tier states and north. The rest of the US was ice free. They animals were killed off not by hunting, but by the 10,800 BC comet strikes that lasted 100 years and burned of 4% of the world’s vegetation, leaving the several foot thick Black Mat earthen layer, as it is called.

But a variation of this story did appear 10 or more years ago, without the pyramid angle.

In North America, it was for all practical purposes, empty of people, there were of course millions of Buffalo and myriad other species of woodland and plains critters but there is virtually no traces of human settlements to any great degree. There just aren't. That is one of the remarkable aspects of the "Old" world versus "New". Whole civilizations and dynasties rose and fell over thousands of years while the NA continent remained unsuitable for human habitation. A mile of ice tends to limit agriculture! Ice Ages suck, one reason why the entire "global warming" scam is particularly egregious.
