Location of Garden of Eden
Genesis 3:23-24 says; "So the LORD God banished him from the Garden of Eden to work the ground from which he had been taken. After HE drove the man out, HE placed on the east side of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life".
Any theory which suggests a present day location of the Biblical Garden of Eden should also locate the way to the garden where GOD placed the guardian Cherubim and a flaming sword flashing back and forth.
Any evidence without these truths is bogus. GOD has kept the location of the Garden of Eden away from human knowledge. No research on the earth can locate the Biblical Garden of Eden.
Only through faith, can we see the Garden of Eden.
