YouTube Description

as posted by the channel

Are humans actually aliens from another planet? SETI (Search For Extraterrestrial Intelligence) Chief Scientist Dan Werthimer explains the concept of panspermia. Comedian Chuck Nice makes it EXPLICITLY clear that he did not make a joke about the word “panspermia”. Planetary scientist and StarTalk All-Star Carolyn Porco illustrates the significance of finding either Earth-like or completely different types of life throughout the Solar System.
