There are other parts of this post that I could debate, but I will confine myself (for now) to just one point.
When you say that God "was lonely" are you saying that there was something lacking in Him? Was He not satisfied with His position/condition? Was He incomplete due to His loneliness and need for love?
I would argue that God created this universe for His own purposes, and for His own glory, but not due to some loneliness or need for love. If so, then He is certainly not God due to the fact that He would not be complete within Himself. (In other words, He would be less than perfect.)
