Fine, however I think people are much better off concentrating on how to live a Godly life and mirror God's truth than spend their time researching the possible location of the Garden of Eden, which as Tuppence posted was buried during the flood.
After the millennial rule of the Lord our eternal home will be a new Jerusalem on a new earth as the old earth will be cleansed with fire. How does Scripture put it:
Revelation 21:1-4
21:1 And I saw a new heaven and a new earth; for the first heaven and the first earth passed away, and there is no longer any sea. 2 And I saw the holy city, new Jerusalem, coming down out of heaven from God, made ready as a bride adorned for her husband. 3 And I heard a loud voice from the throne, saying, "Behold, the tabernacle of God is among men, and He shall dwell among them, and they shall be His people, and God Himself shall be among them, 4 and He shall wipe away every tear from their eyes; and there shall no longer be any death; there shall no longer be any mourning, or crying, or pain; the first things have passed away.
