In the prebiotic world, the chemical evolution scenario proposes that:     Small inorganic compounds gave rise to simple biomolecules from meteorites impacts on the Earth surface.       Large inorganic compounds gave rise to simple biomolecules when sparked by lighting     Small inorganic compounds gave rise to simple biomolecules when dissolved in sulfuric acid     Simple biomolecules were created by primitive bacteria     Small inorganic compounds gave rise to simple biomolecules when sparked by lighting.
