Can you give me an explanation for the existence of universal, invariant, abstract entities? I’m not asking you to explain if they exist, I’m asking you to account for their existence. We would both agree that they exist as we both can add, subtract, multiply and divide.
These abstractions do not actually exist; they do not occupy space and are not made of matter or energy.
I agree that they are real, however.
And, so what that these abstractions are real?
The universe has rules and it is ordered. Going from this observation all the way to the conclusion that God exists will require more proof than anyone has ever provided in all of human history.
