To me this is a terribly poor argument, and also accounts for your lack of manners.
You only give a answer that deflect from the question. You could tell me the truth, that you believe in at least 2 true gods, and that you define one differently from the other, and use language, like, You can be divine but not God.
Theos. How many true Theos? Is this so very complicated? How Many Creator Gods? There is One. In the OT, His Name is given as YHWH, in the NT His Name is Iesous, which we translate Jesus. And to Him, EVERY knee will bow, and every tongue confess that He is LORD, and that salvation is found in none other.
You have a mental difficulty trying to logically analyze Who God is, is that such a surprise?
Not so fast, that only goes towards your rejection of what Triune God means. Here is another sort of a logical argument you may consider.
The Eternal Father eternally loves the Eternal Son. In this way, the truth of the Scripture is preserved, "I YHWH change not". If the Eternal God did not yet have a Son, His is not a Father, but when He comes to have a Son, then He comes to be a Father. Rather than an eternally Fatherly God, He would have become that. He would have changed.
John wrote, "God is love". If YHWH existed alone, whom did He love? He would have come to be loving when He came to be a Father. And why would He "become a Father" or "become loving", were He already full and complete in Himself? To become something "more" is to fill in a lack, and I cannot fathom God lacking anything.
Another side of this aspect that God does not change is our sonship in Christ, and how we understand how this question defines our relationship with God. Are we sharing in the Sonship of the Eternal Son? Or are we sharing with another created being? That goes deep fast.
Much love!
