I have no problem with the notion that the instant of the big bang was the start of time (whatever that means), at least as a practical matter. That doesn't mean -- to me -- that such a place exists now from which some privileged observer can watch over all the centuries. It may be good theology to posit such a state of affairs, but at this stage of my knowledge (scanty) I just don't see it as a scientific possibility. But I'm open to persuasion.
