not so intelligent:
human balance, when we fall we fall hard, and we die.
mouth, we breathe through it while eating, we may choke, and die.
strange fetishes, people like their balls kicked, their faces pooped on, whats so intelligent about that?
fish getting sea-sick, it happens in very turbulent waters.
different organs for different tasks. if i was god, i'd make every living creature a single blob of everything in it.
the problem with religion is that it is used to inventing its own premises for everything, so even when confronted with hard science, it assumes it is allowed to keep inventing premises.
"i see your science, but my premise is to ignore it in the name of jesus"
okay then...
