The more I watch Cosmos, the more I like Carl Sagan. Here’s the opening voiceover from Episode 8:

The sky calls to us. If we do not destroy ourselves, we will one day venture to the stars. There was a time when the stars seemed an impenetrable mystery, but today we have begun to understand them. In our personal lives, also, we journey from ignorance to knowledge. Our individual growth reflects the advancement of the species. The exploration of the cosmos is a voyage of self-discovery.
