This discussion is fascinating but the topic is actually, "why is there something rather than nothing." I wouldn't personally try to propose a reason; it's not my subject, but I have seen quantum physicists proposing that the vacuum is unstable and that nothing can't exist. Can anybody here comment with authority, or at least, good knowledge of the field?
In his book on this topic, A Universe From Nothing, there are two useful definitions for nothing:
o A perfect vacuum
o Not even that. True absence of anything, including the laws of nature.
From a perfect vacuum, it's not too hard to model the appearance of energy and matter from quantum instability. In fact, it seems inevitable.
However, from "true nothingness", an answer doesn't yet to exist.
But, there's no reason to believe with certainty that such a thing as true nothingness (or, anti-something) ever "existed." (It's difficult to word this correctly, because to say that nothingness existed is to say that nothingness IS something, which is not what is being implied here.) We may one day discover that true nothingness is not possible. And given that time itself may not exist, that may eliminate the idea/need that if we go far enough back in time we will find a creation-of-something event. (This is why time is somewhat relevant to the discussion here -- the idea of time's actual existence may be a HUGE player in the eventual answer.)
BTW, I'm no expert on this topic, I just read a lot of science books and articles. Almost daily, in fact.
