We’ve been evolving from the beginning of civilization to a larger and larger perspective of life on the Earth. The next natural evolution is understanding the life in space, that is the fact that the Earth, as Buckminster Fuller used to famously say, is a spaceship; Spaceship Earth. We are in space already. It’s just that we haven’t brought that into our perspective as we live here on earth.
