I think you are trying to understand GOD...good luck. Explain how he can create an oak tree from a seed, or a human being (with all his complexity) from one cell.
You also ask about the names "God" and "The Lord". God was given hundreds of names by his people. Everytime he showed his people a new miracle, they gave him a new name. I can think of at least twenty names for God without even thinking. Because he has several names doesn't make him less, it shows how little we can comprehend his glory and his power.
Already been done. You assume that man can know nothing of the "complexity of life".
Actually, that's the one thing in my faith I'm sure of. That God is absolutely beyond my comprehension. He is so awesome, I could never begin to wrap my tiny little brain around him. I can, however, try to understand who, where, when and why the Bible was written about this awesome, glorious and powerful God.

Yes, I understand this. This is one of the reasons I believe there are separate writers. At one point of history they called him one name and during another point, he was called by another name. Can you imagine someone 2000 years in the future trying to understand why Clinton is called:
Klintoon
x42
Liar in Chief
Sink Emperor
ect ect....
And how hard that would be if we didn't have all the historical documents that explained it?
So rest easy, I'm not trying to understand God. I'm trying to know him better and deepen my relationship with him.
