In Gods infinite wisdom he knew that he would have to place his children on a world that would hold all the needed resources that his children would need to live. He waited through 3.5 billion years of formational organic evolution with the placement of cellular micro-organisms from his realm of existence to bring about his means. At the present time there are also other worlds going through the same process of micro-biotic formation for future worlds that will yet be established with his childrens presents. This process that God has established has always been and will always be the way he creates and assembles places for his children.
