...And this computer, which was called the Earth,
 was so large that it was frequently mistaken for a planet,
 especially by the strange ape-like beings who roamed its surface,
 totally unaware that they were simply part of a gigantic computer program.
 And this is very odd, because without that fairly simple and obvious
 piece of knowledge, nothing that ever happened on the Earth could
 possibly make the slightest bit of sense.
