A nonexistent entity couldn't do any of those things, and since those things clearly have been done therefore that confirms that there are at least enough existent entities to do those things; and with it the concept of entities existing. You're just trying to justify being an edgy nihilist via pseudo-philosophy, so get your faggot ass off of this board.
