Scientists use the results of experiments to draw conclusions, Stanley Miller and Harold Urey conducted an experiment in which they simulated conditions on early Earth. They sealed a variety of gases _____ present on Earth inside a sterilized system, then simulated evaporation and lightning. After a week, the duo determined that the carbon-containing molecules present in the system fused with other molecules to form amino acid-like compounds.
