Another Earth

“Within our lifetimes, we have marveled as biologist have managed to look at ever smaller and smaller things, and astronomers have looked further and further into the dark night sky, back in time and now in space. But maybe the most mysterious of all is neither the small nor the large. It’s us, up close. Could we even recognize ourselves? And if we did, would we even know ourselves? What would we say to ourselves? What would we learn from ourselves? What would would we really like to see if we could stand outside ourselves and look at us?”
