Whether one sees any "evidence" of a purpose in Nature or in the Universe is generally entirely dependent upon one thing, Steve...not the evidence itself, but the prior prejudice that exists in the mind of the observer. You're not going to see what you don't want to see.

Hitler couldn't see any good in Jews. Israel and Iran both can't see any good in each other. They're all mistaken. Human blindness is less often a matter of actual physical (or mental) inability to see something, but rather merely a very strong emotional disinclination to see what one has already decided simply isn't there or SHOULDN'T be or CAN'T be. (your assumption about a divine factor in things)

To admit even the possibility that it is there would be to admit you'd been wrong! And this is what most people are honor bound not to do, simply on the basis of their personal pride and their intense desire to be right all the time and to "win" the argument, whatever the argument is.

And it won't matter. Because the "win" means nothing. And will change nothing.
