Nietzsche and his proposition, God is dead.

In his work The Gay Science, Nietzsche writes:
What is some day or night a demon were to steal into your loneliest loneliness and say to you: This life as you now live it and have lived it, you will have to live once again and innumerable times again; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unspeakably small or great in your life must return to you, all in the same succession or sequence--even this spider and this moonlight between the trees and even this moment and I myself. The eternal hourglass of existence of existence is turned over again and again, and you with it, speck of dust. Would you not throw yourself down and gnash your teeth and curse the demon who spoke thus. Or have you once experienced a great moment when you would have answered him, "You are a god, and never have I heard anything more divine.'

Nietzsche reflects on the futility of meaningless cycles of life in which we wake up the same morning and take the same shower and eat the same breakfast and drive the same route to work and do the same tasks and answer the same emails and have the same meetings and complain to co-workers about the same things and go to the same health club and go home to eat the same dinner and sit down and watch the same shows and brush the same teeth and talk briefly to the same spouse before you lie down on the same bed, to have the same sleep.
Sameness is deadly but Nietzsche postulates, what if there is a mechanistic universe and we are bound to relive every dimension of life, everything is determined. 

Sounds a bit like hell.
