Does it argue for a creator, or does it argue for a cause?
I am satisfied that it is possible to have simply the right conditions for an ur-cause to exist,
I favor the view of a creator over a mere cause, for the extravagance in nature. If efficiency were the driving force, we would not have the ornamentation we see, the paper thin (10 m) rings of saturn, plumage of the peacock, the 10 in the bode law. all done by law.
Laws are the product of a certain intelligence. even if it is an ass'.
To those that point to perceived cruelty, misdesign in nature. I say: visit a slaughterhouse and see how much cruelty is imposed on lesser beings to feed you, or your offspring.
Limited use design seems to be a feature of the past.
