But 32 genera of megafauna vanished from North and South America, and some even in Africa, right at the boundary of the 1200y-long Younger Dryas cold spell, 12,900ya, along with the Clovis culture, and and coincident with a layer of platinum-rich carbon. I'm blaming that on a bolide strike.
History records only a minuscule fraction of the human past, and most of the extinctions (until very recently) occurred well before there were even means to record history. I don't see how you would be able to draw any such conclusion, even if it were true.
