Episode 13

The final episode of The Cosmos was kind of a bitter sweet warning to humanity. Sagan tells the story of how the Spanish conquistadors interacted with the Aztecs and how poorly that went. He then compares our current efforts of space exploration to those of the Spanish and implores us to take pity on any civilizations we may encounter. The episode ends with an overview of the previous twelve and a quote by Sagan that I found to be the highlight of the entire series. He said we need to cherish life and to continue our journey through the cosmos.
