But... but... it's possible that in actuality God is turning off the light and he just designed your refrigerator so that it looks exactly like your light is being switched off by the little button. It is only your atheist, secularist, matarialist bias and your desire to do drugs and consort with loose women that blinds you to this truth.
Nonsense.
Everybody knows it's turned off by the light bulb fairy angel.
And so it might have been, if only loose women had ever shown any interest in consorting with me, and if I had a metabolism sufficently robust to cope with anything stronger than the occasional snifter of Glenmorangie 12-year old single malt...
But I suppose we could offer a menu of theoretical choices on the Eternal Question of the Refrigerator Light, to wit:
Creationist: Using the authority of the sales literature including in the packing crate, the Creationist claims that "Frigidaire so loved its customers, it decrees Non fiat lux! everytime the refrigerator door is closed, thereby sparing us untoward electric bills. To challenge this creed is to risk the wrath of the Frigidaire Corporation and may result in an eternity spent in the foul underworld of spoiled produce."
Intelligent Design: The mechanism for switching off the light inside the refrigerator is irreducibly complex, only a Higher Force (or space alien) could have made it, all of a piece.
Evolutionary: First, there were simple, dark iceboxes...
