15 Clues That Earth Life May Have Come from Space

11. Organic Molecules on Distant Solar System Bodies

Space missions studying Saturn’s moon Titan and the surface of Pluto have uncovered complex organic molecules in their atmospheres and on their surfaces. These discoveries suggest that prebiotic chemistry is not unique to Earth, but is happening throughout our solar system. According to NASA JPL, such chemistry could be a crucial step toward the emergence of life elsewhere.
