WHERE DID ADAM AND EVE GO AFTER THEY LEFT THE GARDEN OF EDEN? This Is A Great Mystery And One That Should Be Easily Solved Because We Know They did Not Go to Mars. From what is described in the Bible there is no indication that Earth was a planet with seven continents.
The Earth appears to have had one large land mass surrounded by water known as Pangaea at the time it was created. The map below is  an indication of how the land mass may have looked at the time of Creation.
If the above map of Panagea is correct, for all we know the Garden of Eden could have been in Sudan or Mongolia or Antarctica, which are all on the east side of the land mass.
The Bible states:
And the Lord God planted a garden in Eden, in the east; and there he put the man whom he had formed. (Genesis 2:8)
Then the Lord God said, “Behold, the man has become like one of us, knowing good and evil; and now, lest he put forth his hand and take also of the tree of life, and eat, and live for ever”— therefore the Lord God sent him forth from the garden of Eden, to till the ground from which he was taken. He drove out the man; and at the east of the garden of Eden he placed the cherubim, and a flaming sword which turned every way, to guard the way to the tree of life. (Genesis 3:22–24)
One thing we know from the Bible is Adam and Eve did not leave the presence of God. Even though the couple were expelled from the Garden of Eden, the fact that Cain had to leave the presence of God indicates that they were still living in God’s presence.
Then Cain went away from the presence of the Lord, and dwelt in the land of Nod, east of Eden. (Genesis 4:16)
Wherever Eden happened to be, Adam and Eve dwelt in the East and Cain went further east. When Earth was flooded in the days of Noah water came up from the depths of the planet. The massive eruptions and movements of the plates caused the land mass to break up into what is known as the seven continents of today. Therefore there is no means of knowing where the Garden of Eden or the land of Nod were situated.
