" It is living, breathing, walking, and talking. Only we cannot see it, because it is happening too slowly. Rock has a lifespan of three billion years. we have a lifespan of sixty or seventy years. And the rock is not even aware of our existence because we are alive for only a brief instant of its lifespan. To it, we are like flashes in the dark. "

― Michael Crichton , The Andromeda Strain (Andromeda, #1)
