IMO, there was no fall. They did exactly as they were supposed to. However, for purposes of this thread, if A&E didn't leave Eden, then nothing would have been invented, discovered, or made by humankind.
I happen to agree. Man in the garden was wild, primitive, running around naked. It seems the story of man becoming civilized. Gaining an awareness of morality, modesty etc...
Man questioned the authority of God. Seeing himself equal to God in being able to choose for himself his fate. Knowing of death and questioning it.
Questioning his current state of existence and seeking to improve it. Forever barring him from the freedom of the wildman's existence.
Not that God punishes man for his choice but in choosing our fate we also are accountable for our bad choices. We suffer the consequences of those choices, good or bad.
It's not a fallen state, maybe that's just a Christian narrative?
It a state of choosing our own destiny. I think that fits to the rest of the Bible. God didn't force us into this state. It a choice Adam made.
Man wants to determine his own destiny. Man is not omniscient so lots of mistakes. God steps out of the way. A few find a way to connect to God and offer guidelines to correct choices. However God never directly interferes, except that little flood thing.
