If there's some non-zero chance that everything could just wink out of existence at any given moment, then I suppose it's inevitable sooner or later, given an infinite span of time. Of course, if we're really talking about infinite length of time, then sooner or later, things will also inevitably come to exist again, so long as the probability of that is also non-zero ;)

But that would be a case of something coming from nothing, which is an absurdity.

Possibly. That description might apply equally well to the possibility that things could just suddenly wink out of existence, though. As Capitalist Eric so ably pointed out, around here we believe in the laws of conservation of mass and energy, young man - and that makes both phenomena rather unlikely, I think ;)

But if we're assuming that that phenomenon is possible - that everything could just up and disappear one day - albeit with a vanishingly small probability, why not further assume that the opposite phenomenon is also possible, albeit with some other vanishingly small probability?

With me? If we start off by assuming "anything" is possible, let's not restrict "anything" to only the things that suit us ;)
