out of Eden
Genesis 2:10
2:10 out of Eden. The geography described in these verses obviously corresponds to nothing in the present world, although some of the names sound familiar. The Noahic Flood was so cataclysmic in its effects (note II Peter 3:6) that the primeval geography was obliterated, with the post-Flood continents and oceans completely different.
The similarity of certain names (e.g., Ethiopia, Euphrates) is best explained in terms of the ascription by Noah or his sons of these names to postdiluvian features which reminded them of antediluvian geographic features, just as the explorers of America often gave European names to American sites.
