In the old GodGab, somewhat before I got here, a poster called Loundry linked to a page about a parasitic nematode called the guinea worm, and asked, as I remember, “How do you explain this?”
It was put aggressively, but I thought it was basically a fair question to pose to theistic creationists. And guinea worms are a particularly unpleasant example, but the same could be asked about human-hosted parasites in general: in whatever sense birds can be said to be designed for flying, it would appear to be equally true that guinea worms are designed to burrow out of human flesh, and that smallpox is designed to produce infectious lesions.
This is unproblematic if the “design” in question is a product of unguided natural selection, but this class of apparently malevolent design seems difficult to square with the attribution of biological complexity to a benevolent creator. What gives?
