More than 3.4 billion years ago, Earth’s hydrogen-rich atmosphere provided the ideal conditions for the formation of life. Electrical activity catalysed the formation of inorganic molecules into amino acids and other organic matter. Earth’s oceans were home to a ‘hot dilute soup’ of molecules that became increasingly complex over time. As these molecules grouped together and separated from their surroundings as nascent cells, the first compounds that could be considered ‘life’ were formed.
