All I can say is that I believe that God can not be fully understood by mere mortals.
Trying to communicate the complexity and scope of the creation of the universe to a then (relatively speaking) very simple-minded people is best accomplished through very simple language. I believe that “The Great I Am” purposefully inspired biblical writings to be easily communicated to those simple people.
I believe God uses all the leeway he knows *WE* need to get his points across. Whether seven days of creation was actually seven gazillion eons is not the issue to me. The issue is that if God wants us to know exactly what all happend during creation to include the mechanics and physics of it, he will grant us the capacity to understand it. And he may yet. It doesn’t appear God allowed that level of understanding during this debate.
