I believe we have these capabilities. It doesn't mean that we will use them. Our future is not assured here. It's not clear that we will survive our own folly, but we have a rare opportunity to do that if we listen and see the messages that nature is showing at us right now, that the finiteness of our own resources and our own planet are showing us right now.

The main problem is that we, as an Earth civilization, have not come to understand ourselves - see ourselves in a cosmic sense at all.

It's rather clear that we've got to do something differently â€" and going into space and learning to utilize these resources, to think differently about ourselves, is vital right now.

There are no unnatural or supernatural phenomenon, only very large gaps in our knowledge of what is natural... we should strive to fill those gaps of ignorance.

Eventually we must leave Earth-at least a certain number of our progeny must as our sun approaches the end of its solar life cycle. But just as terrestrial explorers have always led the way for settlers, this will also happen extraterrestrially. Earth is our cradle, not our final destiny.

The answer to the nature of our existence is somewhere in the middle, and that, of course, is what we're looking for: how to see ourselves in a new picture of ourselves and understand the questions that humans have asked forever, "Who are we, how did we get here, where are we going, and what's the nature of this reality that we're in?"

So, we've gone from covered wagons to going to the moon in just under 100 years. For all the centuries and thousands of years before us, people walked or rode horses, cows, camels or whatever. This so-called modern era, from the late 19th century through now, has been the period of the most amazing development, discovery, innovation and acceleration of change that humans have ever experienced. And it hasn't slowed down yet.
