Life’s Cosmic Genesis: An Earth-Space Collaboration

This episode examines two primary scientific theories regarding the origin of life: abiogenesis, which posits life began from non-living matter on Earth, and panspermia, suggesting life or its components arrived from space. It explores the historical context of these theories, from the "primordial soup" concept and the Miller-Urey experiment for abiogenesis to the idea of space-borne microorganisms in panspermia. It highlights supporting evidence for each, such as the discovery of complex organic molecules on asteroids for panspermia and the RNA World hypothesis for abiogenesis, acknowledging the challenges each theory faces. Ultimately, the episode presents a modern, hybrid view known as pseudo-panspermia, where cosmic materials provided the building blocks that then assembled into life under Earth's unique conditions, emphasizing the collaborative efforts in astrobiology to search for extraterrestrial life and definitively answer this fundamental question.
