Adam-Ondi-Ahman. Supposedly taken from the “pure Adamic language” meaning “the place or land of God where Adam dwelt.” Mormonism teaches Adam-Ondi-Ahman was located in Daviess County, Missouri (Mormon Doctrine, p. 20), showing that Adam lived on the North American continent.
The passage of time has probably made it impossible to know exactly where the Garden of Eden was located. While admitting that no theory comes without difficulties, Dr. Roland K. Harrison, professor of Old Testament at Wycliffe College, Toronto, writes, “On the basis of currently available information it would appear that the one that locates Eden near the head of the Persian Gulf combines the greatest number of probabilities of every kind”( International Standard Bible Encyclopedia 2:17).
The general consensus of conservative Christian scholars point to the Mesopotamian Valley area. The fact that Genesis 2:14 speaks of the Euphrates River, a river still in existence, gives credence to this. Joseph Smith, the founder of Mormonism, and many of his successors have disagreed with such a view and point instead to present-day North America.
