"It is clearly absurd to say that if you go on adding atoms together until they have fused into a complex molecule, that molecule will become capable of self-reproduction. It is like saying that a skyscraper is more capable of reproduction than a bungalow. And suppose life did come into being through some accidental interaction of molecules, sun and cosmic rays; why should it not be content to rest passively? Why should it have been possessed of a desire to persist and evolve?"
