Miller–Urey experiment shows that it is possible for organic components to naturally appear from inorganic ones.
The experiment places water, methane, amnonia, and hydrogen in a flask. The mix was heated and electrical sparks were fired from electrodes. This is supposed to simulate conditions on early Earth.
As the result of experiment, many amino acids form (which are a basis of organic life).
This experiment has important considerations for abiogenesis and RNA World hypothesis.
