How Did Prehistoric Humans Survive the Fear of the Dark?

For 99% of human history, nightfall meant total blindness — and something out there was hunting you. So how did prehistoric humans survive not just the predators, but the terror of the dark itself? The answer rewired the human brain, and you're still carrying it today.
