Yes, people are mostly unaware of the importance of space exploration and colonizing to the future of the human race.
But, it is not a human "fault." We are, after all, unchanged for the last tens of thousands of years. All that has changed is
what we believe. Our belief systems are what shape us and explain where we are. Now, the problem is that our belief system is divided by diverse old religions and united (weakly) by our Secular belief system. The secular belief system's goal for us is "the pursuit of happiness." Does that strike you as a goal that will get us out into space colonies?
We need a whole new belief system to replace all those mentioned above! In
the Atheistic Science Institute - home page I show how to build such a world-view system.
