"In four hundred years, we evolved from a planet of people who are absolutely convinced that the universe revolves around us. No inkling that the Sun doesn't revolve around us, let alone that we are but a minuscule part of a galaxy that contains roughly a hundred billion stars."

"We were like a little bunch of fruit flies going around a grape, and thinking this grape is the center of everything that is. To our ancestors the universe was created for one particular gender of one particular species of one particular group among all the stunning variety of life to be found on this tiny little world."
