You are already diving into cosmology and, frankly, I'm not that interested in it. I guess, my main point of interest is ontology. That being said, I would change your "Define something? A thing. Anything. Existence. Possibilities." into "Define something? A thing. Anything. Possibilities." as "existence" is not a thing. It appears as such only because our human language is rather primitive and cannot even capture the multifaceted nature of experience, let alone the true nature of Absolute in all its breadth. If it could, we would hardly have a need for art or even this conversation.
