Why I follow the Christian way of accounting for the creation of the world.

There are (commonly) at least three categories of accounts of the creation of the world - roughly divided into :  creatio ex nihilo (“creation of nothing"), creatio ex materia (“creation out of some pre-existent, eternal matter”), and creatio ex deo (“creation out of the being of God”).  

For all the arguments that split the Christian world, there is universal agreement that creation occurred "ex nihilo" in great measure because the universal Christian view makes a sharp distinction between the Creator and the Creator's handiwork - that is "Creation."     

Here is how the Gospel of John states it:  "In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through him, and without him not one thing came into being."  (John 1:1-3, NRSV.)   When the Gospel of John states this, the writer is consciously echoing the first words of the Pentateuch itself:  "In the beginning God created the heaven and the earth."  Genesis 1:1 (KJV).

For me, the idea that there is a sharp distinction between the creature and the Creator was something I absorbed as a child.  It is fundamental to the Christian way of viewing the world.   Therefore, if this is one's world view, the only accounts of creation that work are those that preserve the creature-Creator distinction.
