Miller-Urey experiment
Miller and Urey were two scientists who set up apparatus that recreated the conditions that were in the atmosphere 4.5 billion years ago to try and work out how organisms could have been created.
Water was heated to create water vapour which travelled to a flask containing ammonia, hydrogen and methane. They used a series of different electric shocks on the flask and then condensed the gasses. Within a week, they found they had produced the organic chemicals needed for life such as amino acids. But how these organic chemicals turned into life, still remains unanswered, they won a Nobel Prize for their discoveries.
