The surface was searingly hot, as rocks from space plunged down onto it and impacted. So in the late s, a few biologists started a rather quixotic quest. And without genetic instruction, the machinery cannot be assembled. Most chemists believe, as do I, that life emerged spontaneously from mixtures of molecules in the prebiotic Earth.
