The Importance of Genesis 2 24

Young earth creationists brag that they don't have to reinterpret the Bible. But Genesis 2 24 cannot be understood literally, since married couples are not sewn together. The only way Adam and Eve obtained immortality in the Garden was eating continuously from the tree of life. To make them mortal again, all God had to do was prevent access to this sacred tree. This is also supported by the fact that Adam is called dust, which is an idiom in the Bible to denote one is mortal.
