Modern Man has deep and terminal problems - he needs an answer.
But the answer must be very quick and self-validating. (So much so that there is not time or energy for re-stating the question before providing the answer.)
Modern Man needs his world re-making at a blow (With one bound, Jack was free!)
On minute he will be reading, or going about his business - then a momentary pause: he reads, hears, sees something. And very suddenly, there is a simultaneous earthquake, volcano and the formation of anew mountain or an island.
The old has gone - the new is in place: ready to be colonised.
