This led to the birth of the Miller-Urey hypothesis, which suggests that life on Earth began when simple chemicals in the ocean came in contact with energy sources like lightning. According to the hypothesis, the reaction may have led to the formation of the first organic molecules which formed the basis of life on our planet.
Life from lightning—this may sound baffling, but a new study also provides evidence suggesting Miller and Urey may have been right. Researchers who undertook the study argue that when scientists think about the Miller-Urey hypothesis, what comes to their mind is big lightning strikes, but this may not have been the case. Instead, tiny sparks of light from waterfalls or crashing waves gave birth to life.
