Yes, we can. Which is why I don't get the attempt to single out one part of creation and insist that that should "cause" people to recognize that God is the creator. You held out the coexistence of istropy and anisotropy as a "challenge" to atheists, asserting that if they couldn't explain it, they had to recognize Divine Providence. And my question is, what if they can explain it--if not now, someday? Does that somehow diminish the idea that God is the Creator? If there are no logical proofs to find Him, why do you propose one?
A person who will not look, cannot see.
