"We are the representatives of the cosmos; we are an example of what hydrogen atoms can do, given fifteen billion years of cosmic evolution. And we resonate to these questions. We start with the origin of every human being, and then the origin of our community, our nation, the human species, who our ancestors were and then the riddle of the origin of life. And the questions: where did the Earth and Solar System come from? Where did the galaxies come from?
Every one of those questions is deep and significant. They are the subject of folklore, myth, superstition, and religion in every human culture. But for the first time we are on the verge of answering many of them. I don’t mean to suggest that we have the final answers; we are bathing in mystery and confusion on many subjects, and I think that will always be our destiny. The universe will always be much richer than our ability to understand it."
- Carl Sagan (1934 - 1996)
