YOUR BRAIN VS DEEP TIME
The human brain struggles with millions and billions of years. One million years is a thousand thousand years, longer than all of recorded history. The dinosaur era lasted about 165 million years, far longer than mammals have dominated, yet it is still a thin chapter in Earth's 4.54-billion-year story. Geologists read rocks as a calendar far older than any book humans have written.
