There's nothing as in no matter: empty space / no energy. Then there's nothing as in no space at all, where it's impossible for something to exist. And there's the nothing beyond these nothings where even concepts like mathematics cannot exist, which is a total head fuck. I mean can there really be something that nothingy?
When you start thinking (in my case amateurishly) along these lines you find yourself getting closer to something resembling creationism. But then I'm just thinking aloud.
Nothingy.... Creator of all things. Ex nihilo omnia: from nothing came everything.
Neat.
