Sorry, but it’s actually quite easy to ask – so easy that I suppose it’d be quite a task to find people who haven’t asked it in one way or another – and given answers which are at least provisional, logical, reasonable (which is probably as much as anyone could expect).
More than that, I could just as easily reject your rejection; and claim that your concept of rejection also arises from within A.T.U.M.E.
Note that in the O.P., I never claim some kind of perfect epistemic surety – only that the options were ‘logical’.

If I may chime in again (sorry)

I reject the question. It is inexorably impossible to ask, and answer. Because our concepts – any of them, all of them – necessarily arrise from within the A.T.U.M.E. Including our notions of ‘origin’ and ‘beginning’.
