Using numbers as an example, there is only one number that defines absolute nothingness, and as you've already guessed it's zero. Out of the infinite scheme of numbers there is only one zero, and yet, there is an infinite number of other ways to get zero.
1+(-1)=0
(-1)+3+(-2)=0
3*(-3)+9=0
You get the idea...
You can have as many somethings as you want, and they will sum to a perfect nothing as long as there is enough of a counter something. Something and counter something need not necessarily even exist at the same time, as long as the average is equivalent to nothing having existed. You could have:
At T1 Nothing
At T2 Something
At T3 Nothing
At T4 Counter Something
This is very simplified and need not be so black and white, but it gets the point across. You could even get the same result by removing both T1, and T3.
In conclusion, I'm stating that it's much more natural that the world exists in the delicate and ambiguous state of being both something and absolutely nothing at the same time because there are many more ways for it to do so, and is therefore much easier than maintaining, or even attaining to begin with, a perfect state of absolute nothingness.
A something from nothing isn't so improbable. It's probably the status quo.
