Dear student 

It proposes that in Earth's prebiotic history, simple organic matter was exposed to energy in the form of volcanoes and electrical storms. That energy would have catalyzed chemical reactions that, in the span of a few hundred million years, could have produced self-replicating molecules.

Good Luck
