The Garden of Eden is actually located in an unlikely place, in Arizona's Superstition Mountains.
You see, the "Tigris" and "Euphrates" that we now know aren't the same ones that existed back before the flood. Noah and his kids gave these rivers near where the ark landed their names, because they reminded them of the rivers they had back home (think Manchester, NH, New York, Paris, Tennessee, Bill France, etc.).
But the Garden of Eden still exists, in a hidden valley in the Supertition Mountains. You drop down over a craggy, dry, mountain, and there it is: a green, sub-tropical paradise, filled with greenery, exotic birds and crystal streams.
Unfortunately, it is near where Jacob Walz, aka "The Lost Dutchman" struck gold. You've probably heard the stories of how so many people who have went looking for the Lost Dutchman's gold have mysteriously vanished or have turned up dead. Many people blame this on a curse placed on the mine. In reality, it is the work of the Cherubim and flaming sword that God placed at the gates of the Garden to protect the tree of life.
Only one person has stumbled across this valley and survived. Yours truly. The date of birth I listed in my profile is wrong; I was actually born in 1812. I am the Lost Dutchman himself.
Every word of this is true, except those containing vowells, of course. :p
