"I think that in philosophical strictness at the level where one doubts the existence of material objects and holds that the world may have existed for only five minutes, I ought to call myself an agnostic; but, for all practical purposes, I am an atheist. I do not think the existence of the Christian God any more probable than the existence of the Gods of Olympus or Valhalla. To take another illustration: nobody can prove that there is not between Earth and Mars a china teapot revolving in an elliptic orbit, but nobody thinks this sufficiently likely to be taken into account in practice. I think the Christian God just as unlikely." [Bertrand Russell]
