You mean you don't believe that the very small, very hot, universe that existed at T=10-43 was the complete universe and everything in it.
If I meant that, don't you suppose I'd have said something remotely like that?
Since there is no reason for that entity to exist it is either God or was created by God.
Oh, don't be silly.
God said "I AM", which I understand to mean all that there is, was or ever will be.
You're a pantheist now?
So where amy I being silly?
You're ignoring the fact that the word "God" has a meaning.
