Plato and a Platypus Walk into a Bar

Some have argued that because the universe is like a clock, there must be a Clockmaker. As the eighteenth-century British empiricist David Hume pointed out, this is a slippery argument, because there is nothing that is really perfectly analogous to the universe as a whole, unless it's another universe, so we shouldn't try to pass off anything that is just a part of this universe. Why a clock anyhow? Hume asks. Why not say the universe is analogous to a kangaroo? After all, both are organically interconnected systems. But the kangaroo analogy would lead to a very different conclusion about the origin of the universe: namely, that it was born of another universe after that universe had sex with a third universe.
