I prefer Robert Schoch's theory that it was a solar outburst (aka micro-nova) rather than a comet that dramatically warmed the entire Earth. (he was also on Joe Rogan)
A solar outburst would not have deposited a layer of platinum dust.

Island extinctions are a distinct phenomenon. People never managed to drive anything in Eurasia extinct. Even African and Indian elephants still exist. The North American extinction pulse clearly matches the platinum-dust spike from the comet strike.
What about the woolly mammoth, steppe mammoth, straight-tusked elephant, European hippopotamuses, aurochs, steppe bison, cave lion, cave bear, cave hyena, Homotherium, Irish elk, giant polar bears, woolly rhinoceros, Merck's rhinoceros, narrow-nosed rhinoceros, and Elasmotherium to name a few?
Of course Irish elk are island fauna. Lions persisted in Europe into the Classical period, finally done in by Roman industrial-scale collection (not comparable to hunter-gatherer hunting).

It is completely impossible that people drove all these animals extinct with sharp sticks. People lived in the Americas for thousands of years without affecting them noticeably, and then they all disappeared suddenly, 30+ genera strong, along with the Clovis people. We know from polar ice cores that the Americas were shrouded in dense smoke 12,800 years ago from fires started by the comet strikes at that specific tim…
> It is completely impossible that people drove all these animals extinct with sharp sticks. Why? Spears are extremely effective and deadly. And it happened everywhere else. Megafauna also disappeared in Asia, as soon as humans appeared. > People lived in the Americas for thousands of years without affecting them In other words: animals existed for hundreds of thousands of years, but they disappeared within several h…
And continents are big, and people very unevenly distributed. 13kya there were few humans on any continent. It takes more than spears to eliminate mastodons, mammoths, short-faced bears, dire wolves, sabretooth cats, cheetahs, camels, horses, giant sloths in one blow.
Humans did not drive 30+ genera to extinction in the Americas all in under a century, after coexisting for millennia; and did not lay down a film of dust enriched with platinum over the whole continent, or torch it. They did not wipe out their whole material culture at the same time. Nothing Clovis, or any of those genera, are found anywhere above the layer of platinum-enriched charcoal and ash dust.
Horses and elephants did not become extinct in Eurasia, where people hunted far longer. You might notice Africa still sports plenty of megafauna.

Humans could have lived nicely in harmony for hundreds of thousands of years in times of abundance, and when sudden cataclysms caused great famines or suffering they could have resorted to more drastic measures that caused large scale fires. Doesn’t mean this is what I think happened, but sounds just as plausible as comets causing havoc to me. In the end IMO this field has been greatly disserviced by Hancock. The yDI…
Just for the record, Hancock has never promoted aliens. He's dead wrong a great deal, but not that wrong. His crime, though, is to have been annoyingly right too many times, for all the wrong reasons. YDIH is just one such case. Hancock's great strength is that he actually goes to all the places he writes about, and his wife takes great pictures. I forgive all his maundering in exchange for the pics.

This, I think, is part of the controversy. In Australia there's this "noble savage in tune with their environment" thing about the Indigenous people; that they are custodians of the land and live in harmony with nature. The idea that they are also responsible for the mass extinction of the megafauna is incompatible with this idea, and therefore unacceptable.
I've been in Australia 60 odd years, frequently in contact with anthropologists in the Kimberley and PNG. The noble savage trope died out years ago - haven't seen much of that in any serious circles since the back to nature french quasi-anthro types were grooving to La Vallée by Barbet Schroeder (with the Pink Floyd soundtrack). > The idea that they are also responsible for the mass extinction of the megafauna is ..…
