Carl Sagan gives the best speech ever about humanity and how foolish we behave. Pale Blue Dot is one of the most important and reflective speeches about the human condition and our place in the Universe. The Pale Blue Dot is a photograph of Earth taken in 1990 by the Voyager 1 space probe from a record distance of about 6 billion kilometers from Earth, as part of the solar system Family Portrait series of images.
