We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Did time begin at that instant, so that there was no time or space "before"? Or are space and time human constructs? Of course they are. Humans have been making up our understanding of the universe forever. We are wired to do that although we know that it is all beyond our comprehension and our feeble animal senses.
Seriously, the first thing we'd have to do is develop believable science that it occurred instead of the faith-based phenomenon wherein it violated the laws of the universe it purportedly made. We'd probably start by proving the universe is relativistic instead of that the universe only includes local relativistic effects if we stand on one foot and squint.
And so on and so on. Faith in the established standard model is facing some real challenges.
Or as Maudlin recommends, if you spot the sheer implausibility the answer is to stop questioning. (Reminds one of redefining the meter by the changing speed of light - problem of variable light speed solved!)
And which, for those pushing the BB at the days of creation and seeing a fit, isn't a bad idea at all...
