This episode investigates the mystery of how life began on Earth, exploring the transformation from simple chemistry to self-replicating biology. It presents major scientific theories such as the primordial soup model, the RNA world hypothesis, and the idea that life may have originated near hydrothermal vents. Listeners learn how organic molecules may have formed, how RNA might have been the first molecule to replicate and evolve, and how protocells could have provided the structure for early life. The episode also introduces LUCA, the Last Universal Common Ancestor, and considers the possibility of life elsewhere in the universe. Ultimately, it reveals that life’s origins were not a singular miracle, but a complex and astonishing chain of chemical events.
