I've missed a fair bit of this thread and I note that you've had it explained that the RCC accepts the totally allegorical nature of the story.
One reason why the RCC gave away Gensis is because it's so demonstrably incorrect that no serious church would accept it as having any truth value beyond the parable.
Adam and Eve were the only humans? If so, humans would have died out in three generations due to inbreeding and its associated genetic failure. Adam & Eve's grandchildren would have been gibbering mutations, although fundamentals could of course claim that god allowed for that in his manufacture and genetic rules applicable to the entire world of living tissue didn't apply then. Or, obviously in the case of Noah, when god wiped out all humans apart from Noah and his family.
Little things like that are why only a small percentage of christians worldwide believe any of Genesis is literally true*. A few minor churches which started in USA seem to be the main home of this blind acceptance of an obvious "Just So" story.
I did see one howlingly funny bit on the way through - a comment on Pangaea and its relevance to the Noah story. Given that Pangaea broke up some 250
million years before Noah, that's the kind of blatant error I've come to expect from YEC defenders and their allies.
* Churches which accept evolution fully include Catholic, Anglican and Orthodox, which churches make up some 77% of all non-tribal christian sects. (I have no idea what those tribal sects might believe and they are a tiny number anyway.)
