@farmerman,
Creationists are dead. No need to bother for them. The Catholic Church is not creationist, and neither are the main Christian denominations out there. In Islam the evolution theory has yet to be accepted by the laymen, but evolution is taught in high-school in most Muslim countries. So it's only the loners and the fools who still take Genesis literally. They are not worth your time.
More interesting a challenge is 'intelligent design'. I think it is quite possible to prove that evolution proceeds not through design but through trial-and-error and recuperation of old organs to do new things. This was an argument made in an excellent little book by Francois Jacob called "Le Jeu des possibles", which I read in the 80s: if god drives evolution, he is not an engineer but a 'bricoleur', because bricolage is the modus operandi of evolution. Nothing in an organ (e.g. a beak) really seems 'designed', when you look at the evolution that led to that organ and the variabilities there.
A beak is made of bones and keratin, i.e. its covering is a bit like aggregated feathers (feathers are made of keratin)... And that molecule (keratin) is also the one mammals use for their hair and and their claws...
Now you would assume that an engineer as smart as God is supposed to be would have tried to develop a new molecule for a new organ, no? Instead, it's all about recycling something pre-existing to fit it for a new purpose, like a bricoleur will not throw away a piece of wood or metal because 'it can always come handy'. Evolution constantly recycle old stuff to make new stuff, and
that's not how an intelligent designer would do it. That's how an opportunistic bricoleur without much resources would do it.
