When I started understanding how science works, it occurred to me that there just is no evidence that there is a God.

I think it's perfectly OK to exploit the moon. Largely for two reasons: there's no life there, and it is close enough and rich enough in resources to be economically useful to Earth. In the final analysis, everything we do in space, if it does not help the people of Earth, all the people, it's not going to happen.

A new space race has begun, and most Americans are not even aware of it. This race is not about political prestige or military power. This new race involves the whole human species in a contest against time. All of the people of the Earth are in a desperate race against disaster... To save the Earth we must look beyond it, to interplanetary space. To present the collapse of civilization and the end of the world as we know it, we must understand that our planet does not exist in isolation.
