You say, "You said that God invented mathematics". Well, no. I think I said that God 'invented' math. If you will remember, I always, (if I remember to), put 'invented' in scare quotes there, to show it is not a word I feel like does justice to the notion I wish to convey.
You contend, then, that basic fact —what is— has power over first cause, quite apart from being caused by first cause. That is faulty logic. If God is first cause, HE is basic fact, He is the cause of ALL other things, and is not subject to anything from outside himself. As he is the cause of logic and existence and all fact, he has no interest in creating something that does not exist, such as logically self-contradictory notions to which we might attribute valid substance.
I happily admit my words do not do the job in this kind of thing. Words don't fit the comprehension of them, nor does the comprehension fit the reality of them. You want me to ride in your vehicle with you in the driver's seat. No. You probably think you have a destination in mind, or maybe you want to hit a pothole or two, to shake me up. But you are going nowhere with this. Your vehicle is bogus. It is logically impossible for 2+2 to equal 10. Show me why God would want to make 2+2 equal 10 and what it would mean if he did so, and I might consider your POV. The whole notion is silly. It has no power. And God lacks no power.
You are letting words drive your narrative.
