Basically you are saying that the gears evolved somehow. OK, that's a start.
Let's try and get to the meat and potatoes of this though.
Getting to the cornflakes will be easier for you to understand:
Creationist: Design requires a designer – it couldn’t arise by random chance!
Me: Would you say that order requires an orderer?
Me: So why is it that all the small cornflakes send to settle at the base of the box? Do you think it’s because God put them there?
Creationist: No – it must be, well, gravity pulling the small flakes down.
Me: Wouldn’t gravity have pulled the large flakes down as well? Why do the small flakes fall further?
Creationist: I don’t know.
Me: It’s because small flakes fall through large gaps, but large flakes can’t fall through small gaps. The flakes sieve themselves. Random shaking of the box coupled with a non-random filtering law (which we might call “the furthest-falling of the smallest” or “the persistence of the largest”) leads to an ordering of flakes over time, with no intelligent input required. Random shaking is analogous to random mutation, and “the survival of the fittest” (Natural Selection) is analogous to “the persistence of the largest”. Cornflakes and living things are both self-ordering systems, filtering out smaller flakes and deleterious mutations respectively. Cornflakes become more organised over time, and organisms become better-adapted.
Creationist: There must be more to it than that? There must be! There has to be!

OK, that's how it works. It would take you years to arrange every cornflake in order of size... but it happens without you and without any mystic deity, doesn't it?
Tip out the bigger cornflakes and look at the little ones: marvel at the irreducible complexity of the thousands of little pieces, all perfectly sorted!
