You've said a lot of things, but nothing as stupid as what you wrote in the comments here.
You see, the Church was 1) aware of the evidence and 2) put a lot of thought into it. Your examples are not exceptions. The Roman Catholic Church, like all institutions, even ecclesiastical, is populated with humans, who, as you might have missed, are fucking fallible. Oh, and don't go down the papal infallibility route with me buddy because that is a very circumscribed status. The pope is not always, nor often infallible.
On all matters, at all times, the Church put more thought into anything and everything of import than you could ever do in your lifetime. It was not, is not, will not ever be perfect because human beings are involved. So, stop being a petulant ass. Any insitution that has existed for 2,000 fucking years is going to have made some mistakes.
I'm not even a fucking Catholic. There's just something about the hubristic intellectual temperament of atheists that really sets me off.
Oh, and one more thing. I have no idea what you are talking about re: "I do not know how to reconcile an open church "mind" with the sacking of Alexandria's store of human knowledge, either." Last time I heard, the library of Alexandria was burnt prior to the birth of Jesus. Or perhaps there is some other sacking of which I am not aware.
Oh, and one more one more thing, Galileo wouldn't have been shit if monks hadn't hoarded books.
