#2187: Geologic Time
[Megan, arms spread out, is delivering a long-winded explanation to Hairbun and Cueball.]
Megan: Imagine Earth’s history as a football field, from the planet’s formation at one end to today at the other.
Megan: Complex life would be largely limited to the final ten yards. Dinosaurs appear at the five-yard line, the age of mammals happens in the last 1½ yards, and humans arise in the final few millimeters.
Megan: All of written history would fit in a strip narrower than a single hair.
Megan: “Two weeks” would be too small to see even with a powerful microscope.
Hairbun: Mm hmm.
