> Catholics have never really gone for it, even in the US, as far as I'm aware.

Catholics haven't gone for it the way certain branches of Protestantism have because adhering to Young Earth creationism in the face of empirical evidence to the contrary is largely, in those branches of Protestantism, a defense of a particular extreme form of a sola scriptura (a Protestant doctrine which directly contrasts with Catholicisms dual role for scripture and tradition) with Biblical literalism (which is likewise not a Catholic doctrine.)

There are Young Earth Creationists in the Catholic Church, but its a matter of personal belief that is far removed from the core doctrine and identity of the Church.

I was raised Catholic. There is a subset who have definitely gone for creationism. They know that they are not obliged by the Church to believe in the literal story of genesis, but they still prefer it for various reasons.

I have read that there are Muslims, at least in other countries, who are young-earth creationists and anti-darwinists.
