The reason why I say this means nothing is everything, is because based on my logic, due to nothingness possessing a property, it is something. Due to infinity meaning all possibilities, that something of which it is is everything.
As for the finite amount of possibilities argument, I happen to disagree. Things may be finite in this physical universe due to it's empirical laws, however outside the laws of this universe, everything does become possible. Therefore my original stance.
You said, nothingness exsits for a fact. Something is not nothingness, so giving nothingness a property makes it something, therefore nolonger nothingness and therefore doesnt exist. So based on that, its a fact that nothingness doesnt exist. (as you say)
No infinty isnt all possibilities. Iv stated that infinity is something without a limit. So infinite possibilities YES, but infinity doesnt MEAN all possibilities.
Everything outside of this universe, will abid by the laws of its universe, making all possibilities again impossiable. But one could go further to say that there is an infinite amount of universes therefore all possibilities are catered for in each personal universe.
But going one step further, one could still agrue that all possibilities is still impossible because ALL represents a whole, and you cannot have a whole in infinty (as there is no limit)
