What Your Ancestors Actually Feared in the Dark?

Tonight you'll flip a light switch without thinking twice. But for 99.9% of human history, that switch didn't exist — and your brain still hasn't forgotten what that meant. In this video, you'll discover why your fear of the dark isn't irrational at all, but an ancient survival instinct carved into your nervous system over hundreds of thousands of years. You'll learn how your ancestors went from predator to prey the moment the sun went down, why your amygdala reacts before your conscious mind even catches up, and how fire didn't just keep humans warm — it may have given birth to storytelling itself. By the end, you'll understand why that uneasy feeling in an empty parking garage or a dark hallway is less of a glitch and more of a message from deep in your evolutionary past.
