I believe the account of Eden is figurative and might refer more to the War in Heaven than to events on this earth. (Sorry, no explanation here; maybe later.) Due largely to that perspective, I absolutely love the Garden account. I love even more Joseph Smith’s repositioning of the Garden narrative to his own life - in the Missouri revelation and even more so in the temple endowment. I love that the Garden of Eden now symbolically is less than two hours from my house (in TWO locations: Columbus, OH and Louisville, KY) - and that I can leave the lone and dreary world and visit Eden on a regular basis in my journey back to God.
It's one of my favorite concepts within Mormonism.
