I found this interesting online article after listening to Dr. Richard Pratt's lecture on the Old Testament. Wished I was there because he obviously used a map during his lecture. But the website I found is likely a similar research.
I had always thought the Garden of Eden was around the head of the Persian Gulf, but the location of the garden in Israel is...more Biblically correct and sound.
It is interesting that the four rivers in Genesis 2 could be identified as the Red Sea(Gihon), long dried up but still detectable "Kuwait River" as if cutting across the Saudi Arabia Desert in half from West to East(Pison), Tigris(Hiddekel) and Euphrates. This would make the "River" in Genesis 2:10 the ancestor of Jordan River.
The article went on to suspect that the Great Rift Fault system is related to Eber's (Ancestor of the Hebrews) son Peleg (Meaning Earthquake), for in his days was the Earth divided. (Genesis10:25)
