I've often wondered whether something and nothing are just concepts that only make sense from the perspective of a subjective observer. Is `1 + -1` something or nothing? And what is `2 + -2`? Is it something, nothing, or also `1 + -1`? And I could continue like this proving every number you could possibly imagine can exist in some manifestation of nothing. So perhaps we're just one of the infinite manifestations of nothing. From our subjective perspective we are something, but from the perspective of an objective observer nothing is really happening because all the subjective manifestations equate to nothing. I have no idea what I'm talking about, but this always made more sense to me than trying to understand why there is something and how long that something existed for. Perhaps it's both.
