Eden as a sanctuary, not as the entire biosphere
Genesis plants a garden eastward in Eden, with a river that goes out to water other lands. The holy place is a center, not the whole map. Death “in the day thou eatest” is first of all expulsion and spiritual death; Adam lives hundreds of years after the day he eats.
Ancient readers could hold a real Fall without treating Eden as a science paper on global zoology. Restoration saints may read 2 Nephi 2 as describing conditions in the Garden and the human story God is telling, while the wider creation—Moses 1’s many worlds, fossils, predation—has a history God has not yet fully revealed (D&C 101:32–34).
