Genesis 2:8

"Now the Lord God had planted a garden in the east, in Eden; and there he put the man he had formed."  Genesis 2:8

In Hebrew, east can also mean before.  So this verse might be saying the garden was in the east, but it might also just be saying that God planted that garden before man was created.  After all, it was the third day he created all plant life when man was created the 6th day.  God created a home for man before creating man.
