Being can come from non-being

[AFTT47]

Prove me wrong...
I don't think there's a coherent deductive argument that can be made to prove this assertion false. Of course, it is far from clear what exactly is meant by being or non-being, but I wager that for any ontologically interesting definition of these terms, there is no way to show the statement to be fallacious.

Maybe you're right. But I can't make sense of how something that wasn't just suddenly is and with no prior material or whatever.

One thing we must all accept is that reality is not constrained by our ability to understand it. I am already aware of properties of the universe which far exceed my ability to understand.

The universe doesn't care. It goes on existing, completely indifferent to my inability (or your's) to understand it.
