They mixed together simple chemical substances of a hypothetical young Earth atmosphere – water, methane, ammonia, hydrogen, and carbon monoxide, but no oxygen – and exposed this mixture to electrical discharges that were meant to replicate the energy supplied from lightning in thunderstorms. The result: after some time, organic molecules were produced. At…
