god's Farcical Role as 'Explanation'

One of the most common "arguments" that I, as an atheist, hear regarding god's alleged necessity is that, given the incredible complexity (or beauty, or wonder, or intricacy) of certain components of the natural order (i.e., the human eye, the bacterial flagellar motor, the human brain), the only possible explanation for the existence of such complexity is an intelligent designer, which is then read as god. The ludicrousness of this argument cannot be overstated. It is pure farce to point to something like the human eye or the bacterial flagellar motor—much less, with respect to the origins of life, an ultimately simple single-celled organism—and "explain" its existence, as Christians feebly attempt, by citing an omnipotent, omniscient, omnipresent deity whose nature defines good and evil, who developed an infallible plan in which every one of us plays a part, who is concerned with and monitors our behavior, who reigns over heaven, who listens to and occasionally answers prayers that are transmitted by hushed murmuring, and who sent a son—with whom he exists as part of a mysterious trinity—to die for humanity's sins, after which he resurrected his son bodily. To call this monstrosity—this haphazardly stapled-on appendage—an "explanation" is to make oneself appear to be a fool.
