Life on Earth needs an origin story, and this film lays out the competing scientific answers to how non-living chemistry became the first living cell. It walks through abiogenesis experiments that try to recreate primordial conditions in the lab, from the classic Miller-Urey spark-in-a-jar setup to more recent attempts at building self-replicating molecules, alongside the panspermia hypothesis that the raw ingredients, or even microbial life itself, arrived on comets and asteroids. Researchers explain what makes RNA a plausible starting point for heredity before DNA existed, and why hydrothermal vents and hot springs keep coming up as candidate nurseries for the first cells. The film treats this as an open scientific problem rather than a solved one, weighing the evidence for each theory against what meteorite samples and lab chemistry can and cannot show. Expository narration carries the argument, backed by animation of molecular processes and interviews with scientists working on the question, tracking a field that is still testing its own best guesses.
