I'll start with this, Vlad.
1. God is the one and only God. There is no other God and there will never be any other "gods". He is ominiscient, omnipotent, and ominipresent. He is spirit only--he was never an exalted man.
"Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me." Isaiah 43:10
"God is a Spirit: and they that worship him must worship him in spirit and in truth." John 4:24
