[Teenaged Fool]

If you put all the parts of a motorcycle in a bag and shook it for billions of years, i would wager eventually you would get something vaguely motorcycle-like in the end. Just like how eons of time allowed for simple primordial elements to combine into the complex proteins and compounds that organic matter is made of. The chances of shaking motorcycle parts into the shape of a motorcycle over millions of years is probably somewhere near the same odds of carbon nitrogen and other elements organizing themselves into living things around us today. The only difference is that environmental factors cant cause your motorcycle parts to line up in ways that better enable it to run. To be honest the chance of a person shaking a bag of parts into a motorcycle makes more sense to me personally than an invisible wizard snapping his fingers and causing a motorcycle to appear from mid-air.
