In Genesis 3:22 through 24 KJV man is ejected from the Garden of Eden and Cherubims are stationed on the East side of the garden to prevent man going back and eating from the tree of life.
22 And the LORD God said, Behold, the man is become as one of us, to know 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:
23 Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
24 So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
From the fact that the Cherubims were stationed on the East side it would necessarily portend that the rest of the World would be to the West otherwise they would have been stationed all around assuming that entry could be gained through other than the eastern gate.
My question then is assuming that the Garden of Eden was a physical place why isn't it known of today, and if it is not a physical place then there are whole new batch of questions in my mind.
