From the last dinosaurs to the first humans was 66 million years, it wasn’t that fast.

What is weird is that humans are so intelligent. It’s much easier to evolve big teeth and ripping claws to make you the dominant species then it is to evolve a highly complex brain.

It can’t have been the extinction of the dinosaurs that had that impetus because by the time the first proto humans were around any effects of the asteroid impact would have long since dissipated. So there must have been some other threat that arose that was dangerous enough to require us to evolve to survive it, but was slow burning enough that it gave time for that evolution to happen. It also left no evidence.
