This analogy – like its modern descendant, the Flying Spaghetti Monster – makes a great deal of sense if you believe that the idea of God is an absurdity dreamed up by crafty clerics in darkest antiquity and subsequently imposed on the human mind by force and fear, and that it only survives for want of brave souls willing to note how inherently absurd the whole thing is.
I’m fairly certain that atheists’ diselief in God is not contingent upon the assumption of some conspiracy of Jesus Christ Superstar-type priests looking to fool the drooling masses with a prefab script. It is the lack of any evidence that is the beginning and end of the story.
Douthat doesn’t discount atheism entirely, but if you don’t disbelieve within his parameters, you’re probably just a weirdo (emphasis mine):
But it is one thing to disbelieve in God; it is quite another to never feel a twinge of doubt about one’s own disbelief. And just as the Christian who has never entertained doubts about his faith probably hasn’t thought hard enough about the matter, the atheist who perceives the Christian God and the flying spaghetti monster as equally ridiculous hypotheses really needs to get out more often.
Ouch! But truly, the best reason I can think of that one would not see the two ideas as equally absurd is that the concept of God is either incredibly vague or incredibly anthropomorphic; that is to say, fuzzy yet familiar enough not to jump out in our own minds as patently nutty. Orbital teapots and sentient pasta, not so much. But there is equal evidence for all of these things: none.
