I always found weird all these discussions about what exists and what not exists in that there is a distinct lack of focus on what existence means.
Even if the only thing to exists (existence level 0, if you wish) was some vague "cognitive activity" would I not exist (existence level 1) in that cognition?
Unless you assume that there is a certain divine level and you are conjecturing about your relative existence compared to it what is the object of talking about the possibility of non-existence?
In my mind this is similar to the theological mind-trip about the universe being a simulation; it is clear that I exist in some sense, rather than focusing on whether my existence is fake or "not real existence" is it not more reasonable to focus on how my existence relates to other existences?
