You're right. 99.99% was a hyperbolic estimate. Although I don't think 9 out 10 would be an exaggeration; in fact I think that's pretty safe. I would say evolution makes the grade among scientists simply because it rests on the soundest available scientific evidence. It does indeed challenge the Christian creation story if you take that story literally, and (admittedly) that's the way it's largely been taken throughout the Church's history. So whether the Church can adapt remains to be seen. I think Western theology has the toughest hurdle to overcome due to its unique doctrine of Original Sin, which evolution reduces to the level of a fairy tale. The Eastern Churches don't have to deal with this so much, but their theologians bristle at evolution anyway since they've always had such an innate conservatism and traditionalism.
