The Garden of Eden appears to be an anomaly. It was unique and set at a particular place on the earth for God to create in two particular people, Adam and Eve, the psychological and sociological characteristics that would eventually come to all humanity.
We focus on the disobedience of Adam and Eve and the curse they brought by eating the forbidden fruit. We tend to forget all the other things that occurred in the garden. Adam named animals and found he was not one of them and so could not be satisfied with their presence. God created Eve and marital relations had their beginning. Adam and Eve were given the ability to act outside their instincts. This is why Eve was able to think about her choices, and shape her replies when Satan tempted her. Adam did the same when Eve tempted him. In one of the great ironies of the story, they came to have knowledge of good and evil so they and their descendants could know that they needed the redemption God would provide.
