Good chink in the aetiology. If God designed an imperfect world, where animals were adapted to eat other animals, and humans with their fire, tools, and capable jaws could derive sustanance from animals, and man was put here to be tested, then there'd be little problem with the aetiology.
But the idea that animals were perfect, viruses were perfect, mosquitoes were perfect, sabertooth tigers were perfect, kimodo dragons were perfect, great white sharks were perfect, rattlesnakes were perfect, baleen whales were perfect, spider wasps were perfect - well, that causes problems with that aetiology. God went to an awful lot of work to create these potential adaptations that were not intended to be adaptations, only for Adam to screw up and these non-adaptations were corrupted instantly from a peaceful costly signalling of useless ornament or procedure to an extremely convenient system for eating, reproducing, etc. I await TWS putting in a cartoon of a great white shark eating kelp, of a rattlesnake sinking its envenomating fangs into a tomato, etc.
Sustaining idiocy in the face of common sense is the conspicuous display, or costly signalling, of a robust belief system (impenetrable faith) organized around the alpha prophet, entirely engineered as a shiboleth or challenge/authentication system of vetting allies in that belief system. Has nothing to do with making sense. Has to do with identifying allies. With allies you share or entrust wealth, build marriage alliances, build power bases, maintain quid pro quo or patron/client relationships, even build your own little reality inside of which all is true and outside of which all is false. Has not the first thing to do with making sense.
