Also, there is a very serious flaw with arguments that take the form "God could not make universe X because it presents some logical contradiction Y".
This kind of argument presupposes that logic exists at the time of creation, and that God's acts of creation are subject to it.
So if logic already exists at the time of creation, either God created logic or he didn't. If he did create a logic, then he could have created it however he wanted.
If he didn't create logic, well, either nobody created logic and it's always existed, or something else created logic. And we're back to square 1.
