Amadiro said, "I see no virtue in the question. We need not seek for complex answers to the 'Why?'. Random processes play an important role in evolution and, to some extent, in all things. If there are millions of habitable worlds, evolution may proceed on each of them at a different rate. On most, the rate will have some intermediate value; on some the rate will be distinctly slow, on others distinctly fast; on perhaps one it would proceed exceedingly slow and on another exceedingly fast. Earth happens to be the one on which it proceeded exceedingly fast and we are here because of that. Now if we ask 'Why?' the natural—and sufficient—answer is 'Chance.' " Amadiro waited for the other to betray the crank by exploding in rage at a preeminently logical statement presented in an amused way,
