It was a dogma throughout most of the 20th century that quantum science only applied to subatomic matter, and we now know that not to be true. One of the major discoveries was Quantum Holography.

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 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?"

When I went to the moon I was a pragmatic test pilot. But when I saw the planet Earth floating in the vastness of space the presence of divinity became almost palpable and I knew that life in the universe was not just an accident.

When I learned that aliens really do exist, I wasn't too surprised. But what did shock me when I started investigating extra-terrestrial reports a decade ago is the extent to which the proof has been hushed up. It isn't just the US government which has kept quiet about alien visits. It would be arrogant of an American like myself to assume that ETs would only choose to visit my country. Indeed, I've heard convincing stories about governments all over the world that know of alien visits - including the British government.

Perhaps people need to understand some history here. Rene Descartes, in the late 16th, early 17th century, postulated that body, mind, physicality and spirituality belonged to different realms of reality that didn't interact. On a positive side, it got the Inquisition off the backs of the intellectuals and they quit burning them at the stake for disagreeing with the Church.

Let me put it in a rather larger picture framework. Let's go to the longest time frame, the time frame of the life of our sun. As a star, our sun is about halfway through its life cycle. In the long run, we only have a couple of billion more years likely that we can inhabit this planet. By that time, we're going to have to be out of here before our sun dies. Now, I don't think we need to wait that long, and we certainly shouldn't wait that long. At the moment, we are not on a sustainable path.
