GOD said to the serpent since you have done this cursed are you above all creature I have made and he said to Adam and Eve since you have disobeyed me you are no longer allowed in eden and then GOD placed a flaming sword in the entrance of eden so no human could ever get back into eden again. The reason GOD doesn't want anyone to go back into eden is bacause there was one more tree that Adam and Eve had not eaten and that was the tree of life which grants you the ability to live for ever.
