But, according to creation theory, the pebble and the mountain *were*
designed by God, since He designed and created *everything*.  Are you
sure you know design when you see it?

I can make a pretty good argument against the existance of a reliable,
nontrivial (i.e. doesn't just say that everything was designed) method
(algorithm) for determining whether an object was designed or not. (Some of
you may recognize the following as similar to the nonexistance proof for
algorithms solving the halting problem)  The argument goes something like
this:
	Assume we have a method for determining whether objects were
	created or not.  We should be able then to design and build
	an object not meeting the test for design.  Since the object
	was designed, but the test marks it as undesigned, the test
	must not be reliable.

The only thing that keeps this from being a rigorous proof is that "should
be able to" part, but I think that's a reasonable claim.  It may be hard to
build a rock from scratch, but then, people don't usually try.  And when
they do, they often succeed (ever heard of manufactured diamonds?).
