Apologies in advance for posting what should be a link but it is too funny to lose it in the ever effervescent rolling listing of links. 

Spectator's competition: a letter of resignation from God 

Basil Ransome-Davies
Let me admit that when I started this project it was in a vein of hope and belief but also of sobriety. I reasonably concluded that my power and knowledge, being limitless, would ensure a transcendent outcome. Even when I was obliged to drown nearly everyone I dismissed the issue as a glitch. Something went badly wrong, however. I chose natural selection as the instrument of my vision of a biodiverse world, but also to build in a sense of advancement, from lower to higher forms, rather than a static perfection. Homo sapiens would move beyond animal instincts to refined emotions, art and the practice of reason. The pattern would work out. My plan would be accomplished. Unfortunately you seem to be a rabble of blind, mutually destructive fucking maniacs. I can accept no further responsibility and hereby resign.

Being omniscient, I should have known: Creation is one thing, its administration quite another. I might apologise for my somewhat simplistic approach to management in earlier millennia — the autocratic Commandments, the pernickety dietary laws, the ten frankly melodramatic Plagues — were it not for the failure of my later, more peoplecentric managerial approach. My son’s unfortunate work-experience placement in Palestine particularly discouraged me — nepotism was never my intention and your reaction, even today, seems disproportionate. I think it is to my credit that I have remained, albeit in a privately consultative capacity, until now. Nevertheless, I resign. Lucifer, who has been rather literally shadowing me for some time, and who seems to possess a surer understanding of human motivation than I, has already suggested himself as successor. I am off to one of those other Universes, whose existence convinces your physicists in a way my own never could.
