Garden of Eden - location for more information: there are many theories about where the Garden of Eden was located and there are many who believe the garden did not have a physical location. The continued deposition of sediment from the River Tigris and the River Euphrates has moved the shore of the Gulf eastward from Ancient Sumer. The light blue in the western Gulf shows that the process continues. See entries for
Ur and
Eridu. And see discussion of possible locations at
