It goes like this: I own an SUV, but am not a mechanic. I know that when I turn the key in the ignition, the engine starts. I do not know how the engine works, but I accept that (today at least) it does. According to "irreducible complexity," the fact that I don't know how the engine works doesn't mean that someone else might know. Instead, I am supposed to believe that God made the car. And therein lies the hubris.
