Perspective - Yuval Harari

"Spread both your arms out as wide as you can and let the distance between your two hands represent the history of the Earth. How much of this distance would human history take up? One arm up to the elbow, maybe? A hand? A finger? Not even close. If you wanted to see the space taken up by humanity, you’d need a powerful microscope."
