A researcher claims that the true location of the biblical Garden of Eden is near the Great Pyramid of Giza, based on biblical and medieval texts. He argues that the Gihon river mentioned in the Bible is actually the Nile. The researcher also suggests that the Great Pyramid of Giza was built near the former location of the Tree of Eternal Life. He believes that the pyramid fulfills the notion of immortality ascribed to Adam by God. Most biblical experts still believe that the garden was located near the Tigris and Euphrates rivers in southern Iraq.
