You wish that is what Hebrews 1:8 said! o' God means of God. Hebrews 1:8 merely quotes Psalms. Angles are of God. Doesn't make them God. What part of the 1C do you not get?
Complete and utter RUBBISH! it that case the same can be said for every time GOD is used for the Father, that it means no more than a "divine being". Your arguments are based NOT on what the Bible teaches, but your heretical views as you are a Unitarian, which is DEMONIC!
