Why your brain cannot distinguish a million years from a billion
In short: Human intuition is biologically hardwired to perceive time in seconds and seasons. This video explores why our brains struggle to grasp the vastness of deep time, and what that cognitive failure reveals about the limits of human memory and imagination.
Deep time is a scale that fundamentally breaks human intuition. Because our brains evolved to navigate immediate environments—judging time by seconds, seasons, and individual lifetimes—we lack the cognitive architecture to differentiate between massive geological spans. When faced with figures like 300 million years or one billion years, the mind defaults to a generic category of "a very long time." ,
