I was raised Catholic In the USA, east coast and Pennsylvania. I have no recollection of Creationism until at least at college. We were taught Genesis but it seems to have presents more as allegory than literal truth. I went to a Catholic college(even though extremely lapsed as a Catholic by 18) in Duluth, MN. That would be the first time I had some contact with creationism. The creationism did not come from instructors or the priests but rather the more fundamental students. Since the priests and nuns I have been associated with in my life tended to be highly educated, I think there was little chance creationism would find fertile ground in their minds. That would have been early '80's.
My wife believed the Noahic flood when I first met her 10 years ago. I think my influence and her training as an M.D. has successfully disabused her of that silly notion. Her religious(I call them liberal fundamentalist) family has become noticeable less religious through the years.
