As every good and intelligent atheist knows, but often refuses to acknowledge through ceasing to reiterate, no analogical appeal asserting the ridiculousness of a belief in God will ever demonstrate anything to a believer, except that the atheist considers the idea of God and consequent belief in that idea to be ridiculous.  Like many sad but momentarily useful philosophical demonstrations, the Teapot analogy(and its successors) begs its own question.  It begins with a preposterous proposition, continues with an irrational comparison and concludes therefore that the thing to which the Preposterous was compared must also, therefore, be silly.  But very easily, we could begin with something less ludicrous, more contextual, and equally obscured from empirical observation.

Flying Spaghetti Monsters and Celestial Teapots (though their faces will never shine down on us with benevolent grace) do serve to illuminate one not very elusive truth; Atheists think the idea of God is stupid!
