I think that's an interesting question, I hadn't ever thought about the Adam and Eve fallen question. I believe these are good questions to ask, I personally think that we should question everything in the Bible to try and learn more. That's how I learn at least, to simply repeat something without thinking means nothing, but to truly question and try to understand my religion/beliefs/God better is of paramount importance to me.
I've been given the eyebrows-up look when I ask questions sometimes, but oh well. There are a lot of things in the Bible that show God to be truly loving, and others that at first look show him to be horrific and brutal. Sorting through those and trying to understand what things REALLY mean helps me to keep my faith and not be somebody who grabs one verse and uses it to condemn an entire faith system. There are many things in the Bible that I still don't understand, and at times disgust me, but I keep plugging away because if that's what God did or wants, well then it's right, and it's my job to learn more and grow.
Good question
