I just want to hit on the notion of events here, the view of time in current general relativity is that time and effects of time is inherently ingrained within the universe.This is why you have Gravitational fields affecting time , As well as speed affecting time.Obviously if time is part of the universe this implies that time didnt exist without the universe.Hence the concept of "first" and "last" hold no meaning when referring to "pre universe".Infact most prominent atheists use this to claim that the universe could have just come into existence as there was no such thing as time.
The concept of Allah is such that he exists .In the frame of the universe he has "always" existed (as time came along with the universe.)
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.
