This early Earth contained large quantities of hydrogen, nitrogen, water vapour, methane and ammonia. In 1953 Stanley Miller famously discharged electric sparks into a mixture of these gases. The result was the formation of amino acids - the building blocks of life. Energy sources in the early Earth included the sun, electrical discharge from lightning, radioactivity and volcanic heat.
