It's INCORRECT to label an "Incommunicable attribute" of God as if He's somehow "unable" to do something, in this case communicate His attribute of ETERNALITY and UNCREATEDNESS.

God can NOT lie.
God can NOT do anything CONTRARY to His own Holy nature.

Since God is UNCREATE (we're talking about the biblical deity and NOT the Mormon one, btw), He is UNIQUE, in a cl*** by Himself (I'm referring to God: Father, Son, and Holy Spirit...NOT just the "Father").

So the answer is NO, God is "unable" to make another DEITY such as Himself, because THAT "deity" could NOT BE UNCREATED.

Got it now?
