Molecules. All living things consist of organic molecules. .. How did these building blocks of life first form? Scientists think that lightning sparked chemical reactions in Earth’s early atmosphere. They hypothesize that this created a ‘‘soup” of organic molecules from inorganic chemicals. In 1953, scientists Stanley Miller and Harold Urey used their imaginations to test this hypothesis. They created a simulation experiment to see if organic molecules could arise in this way .
