I’ll address these two as an example.
Isaiah43:10,11 — … before me there was no God formed, neither shall there be after me … … I, even I, am the LORD; and beside me there is no savior
Isaiah44:6,8 — … I am the first, and I am the last; and beside me there is no God …
It’s important to look at the context used in the Old Testament. For example Isaiah 47:8-10 depicts the city of Babylon as saying:
Quoting verses in a different chapter isn’t using the quotes “in context.”
Therefore hear now this, thou that art given to pleasures, that dwellest carelessly, that sayest in thine heart, I am, and none else beside me ;
These are arrogant words reserved for the one creator God. So they support the biblical teaching of one creator God.
Psalms 82:1 God takes a stand in the divine council, gives judgment in the midst of the gods .
God has taken his place in the divine council;
in the midst of the gods he holds judgment:
“How long will you judge unjustly
and show partiality to the wicked?
Give justice to the weak and the fatherless;
maintain the right of the afflicted and the destitute.
Rescue the weak and the needy;
deliver them from the hand of the wicked.”
They have neither knowledge nor understanding,
they walk about in darkness;
all the foundations of the earth are shaken.
I said, “You are gods,
sons of the Most High, all of you;
nevertheless, like men you shall die,
and fall like any prince.”
Arise, O God, judge the earth;
for you shall inherit all the nations!
Psalm 82
Christians are monotheists who, like Judaism, believes in one uncreated creator God. So if the Bible refers to gods in plural, we know they mean something different from the one uncreated creator. It is the rational conclusion. Mormons reject reason, so they find it difficult to see the obvious conclusion.
For the third time, are you referring to creation ex-nihilo, or creation ex-materia?
There is one only one creator; only one God. You seem to want to make a distinction without a difference.
