Micah Hanks, 2021-01-18: Cosmic Ancestry: Panspermia and the Origins of Life

What are the origins of life on Earth? Did the building blocks for life originate here, or did they travel to our planet in the distant past from someplace further out in the cosmos?

On this week’s edition of The Micah Hanks Program, we explore the idea of panspermia or “cosmic ancestry,” which supposes that for life to exist on a planet like ours may rely on extraterrestrial factors. We also look at ideas about whether aliens might already recognize that we exist but choose not to communicate with us, or even whether alien life may already exist right here on Earth.
