In 1953, Urey and Miller conducted an experiment to prove this theory. They created the conditions of primeval earth − high temperature, volcanic storms, reducing atmosphere containing CH4, NH3, etc at laboratory scale. They then stimulated electric discharge in a closed flask containing CH4, H2, NH3 and water vapour at 8000°C. They observed formation of amino acids. In similar experiments others observed, formation of sugars, nitrogen bases, pigment and fats. These small organic molecules are the building blocks for proteins & other components. Hence, this experiment supported that life has come from pre-existing non-living organic molecules.
