Lightly seared on the reality grill.
You think too little of yourself. What makes you think we can't?
Can't what? We obviously can't use temporal concepts to explain the existence of time because it doesn't make logical sense. More generally, intuitions based on our experience have frequently been shown to be fundamentally wrong even within the universe, so trying to extrapolate beyond it seems rather foolhardy or arrogant to me.
Correct.
Hence the infinite regress.
