Garden of Eden

According to the first story of Genesis, the Garden of Eden is the utopian garden where God put the first humans Adam and Eve to live. The problems associated with the garden are discussed along with original sin.

After the exile of Adam and Eve, God posted angels and a spinning sword (an object not yet invented at that point in history) to guard the garden and prevent mankind from returning. 

It is believed to have been located in Mesopotamia, based on the scripture at which says: "10 And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads. 11 The name of the first is Pison: that is it which compasseth the whole land of Havilah, where there is gold; 13 And the name of the second river is Gihon: the same is it that compasseth the whole land of Ethiopia. 14 And the name of the third river is Hiddekel: that is it which goeth toward the east of Assyria. And the fourth river is Euphrates."

Interestingly, if these rivers really did run through the garden, then it would tend to conflict with the concept of the Great Flood which would most likely have changed the geography to a point that these rivers would be unrecognizable at best.
