The search for the Garden of Eden has gone on since Noah stepped off the ark. The exact location is speculative at best. Nevertheless, we can infer some things, without going beyond Scripture.
Genesis 2:10-14 Updated American Standard Version (UASV)
10 Now a river flowed out of Eden to water the garden; and from there it divided and became four rivers. 11 The name of the first is Pishon; it flows around the whole land of Havilah, where there is gold. 12 And the gold of that land is good; bdellium and onyx stone are there. 13 The name of the second river is Gihon; it flows around the whole land of Cush. 14 The name of the third river is Tigris; it flows east of Assyria. And the fourth river is the Euphrates.
The Euphrates has long been known, as is also true of the Tigris. However, the identity of the Pishon and Gihon has never been identified. In addition, the topography today does not have the Euphrates and Tigris Rivers proceeding from a single source. The earth-wide flood that Noah and his family survived in the ark would explain the change in topography. Some rivers would have been filled in and others would have had their courses changed. Even a tremendous local flood can change the course of a river, such as the Mississippi in the United States.
The long accepted location of the Garden of Eden has been the mountainous area about 140 miles Southwest on Mount Ararat, in the Eastern part of Modern-day Turkey. Again, the mountains could be a result of the flood, or it could be that a mountainous range surrounded the Garden of Eden, giving us the reason why cherubs protected only the East of Eden.―Genesis 3:24.
Sadly, it is true that most modern scholars dismiss the Garden of Eden as a legend or a myth, not being a real historical account. Nevertheless, this writer, as well as many other conservative scholars, accepts the historical reality of the whole of Genesis. The account itself is highly detailed, giving the sense of a historical narrative, not a myth or legend. Moreover, we do have geographical evidence, as two of the four rivers identified are still in existence today. In addition, verse 14 says, “The name of the third river is the Tigris, which flows east of Assyria. And the fourth river is the Euphrates.” This location is present day Iraq.
