Getting back to your a posteriori reasoning about autos. If you had a car that kept breaking down all the time, what would be your opinion of the Designer? Humans have to nurse a poorly-designed system through life, a system that not only becomes disabled through poor design,relies on a fixed minimum of resources to avoid death in minutes,hours,days, but, also has to be kept in good condition to resist attacks by bacteria designed by the Creator-of-all-things to destroy the human system. With limited self-repair, wouldn`t you think an Intelligent Designer would do a better job of his Supreme Creation? Only a person locked into a religious view would accept the idea of a benevolent Creator with the constant evidence of faulty design around us.
