Lightning origin of life theory

Lightning theoryPrimordial soup (f) lightning theory
The lightning origin of life theory postulates that billions of years ago a lightning bolt (or intense period of electrical activity) hit a warm pond or primordial soup and thus triggered, sparked, or activated the first reactions of life, or something along these lines.
In origin of life theories, lightning origin of life theory holds that the first form of life on earth originated when a lightning bolt (or period of intense electrical activity) struck a warm pond or primordial soup and thus started the first chemical reactions of life, first life form, or something along these lines.

History
The lightning origin of life theory seems to have been first put forward by English naturalist Charles Darwin in 1871 as follows: [1]

“The original spark of life may have begun in a warm little pond, with all sorts of ammonia and phosphoric salts, lights, heat, electricity, etc. present, so that a protein compound was chemically formed ready to undergo still more complex changes.”

The 1952 Miller-Urey experiment famously tested this theory, the results of which showed that sparks ignited in a chemical broth, over several days, could make amino acids.
