Four and a half billion years ago Earth is a chaos of meteorite strikes, volcanic gas, and lightning through a thin atmosphere, and somehow chemistry crosses into biology. Mineralogist Robert Hazen travels to an ancient market in Morocco and out into the Australian Outback tracing his own counterintuitive argument: that ordinary rock did not just provide a stage for life's beginning but actively shaped it, and that early microbes then returned the favor by helping generate hundreds of minerals that did not exist on the young planet. The film follows Hazen's fieldwork and specimens as evidence for this co-evolution, treating mineralogy and biology as a single feedback loop rather than separate stories. Instead of settling on one origin-of-life scenario, it uses Hazen's mineral evidence to reframe the question itself, asking how much of what we call geology is actually a record left by life. The Moroccan bazaar and the outback rock formations serve as the two clearest stops on that argument.
