If you define everything as all that exists, then you have placed a constraint on the concept of everything. It’s like saying a blue ball is not part of “everything red” unless it’s also red,
but up know what I mean .
In your case, something that does not exist is not something that exists, quantum bs aside.
Also, when I say binary, I meant in terms of true/false, something that either is or is not and cannot be in any other state.
As far as existence is concerned, I’ll be the devil’s advocate and state I believe you can’t prove we, or anything exists. All of what we call reality is observed within our own subjective perception. I cannot prove that you see it experience what I do. You could be an illusion generated by my own mind (metaphysical solipsism).
Edit: For those of you who love anime, the Melancholy of Haruhi Suzumiya is based around a creationist ideal of solipsism. Regardless of your beliefs, I highly recommend the show.
