" The rain would fall, the plants would grow, the animals would eat and kill and die and grow again, and the ghost of sentient life would fade away, an insignificant blip in the memory of the Earth. Someday, a million years away, maybe a billion, when another species evolved or awoke or descended from the stars, would they even know that anybody had been here? "
