Before the first cell existed, Earth had only rock, water, gases, and repeating chemical reactions. Meteorites carry amino acids and carbon compounds. The Miller–Urey experiment showed that simple gases, water, and electrical sparks can produce amino acids. Yet an amino acid cannot copy itself, build a cell membrane, or preserve energy.
