Perry: every argument you make for something needing a beginning is a contradiction and an argument against your own belief in a super being with no beginning.
So carry on, tell us more about the god that can't exist based on your own logic.
Actually I think he is referring to the fact that everything that HAS A BEGINNING has a cause.
There is nothing in that argument that is referring to subjects which have no beginning.
So there is nothing that requires the argument to also apply to an eternal God.
