40,000 years ago, early humans painted hands on the wall of a cave. This morning, my baby cousin began finger painting. All of recorded history happened between these two paintings of human hands. The Nazca Lines and the Mona Lisa. The first TransAtlantic flight and the first voyage to the Moon. Humanity invented the wheel, the telescope, and the nuclear bomb. We eradicated wild poliovirus types 2 and 3. We discovered radio waves, dinosaurs, and the laws of thermodynamics. Freedom Riders crossed the South. Hippies burned their draft cards. Countless genocides, scientific advancements, migrations, and rebellions. More than a hundred billion humans lived and died between these two paintingsāone on a sheet of paper, and one on the inside of a cave. At the dawn of time, ancient humans stretched out their hands. And this morning, a child reached back.Ā
