Simple coherency doesn't mean truth, what you're doing is begging the question. I don't understand general relativity but if the concept of time doesn't apply before creation then the concept of cause and creation are both unintelligible because they presuppose chronology. You've painted a situation that's simply mystical. Under such a situation any bare assertion is as good as any other and nothing is proved.
Good reply nonetheless.
What more of an answer than that do you need?
