The only thing constant is yourself. How can you be sure anything else is real, is this all a fabrication? A fabrication with false logic placed behind it, like a dream.
You can, real or fake both are trying to give an image one is real one is fake. you know whats not fake cause you know it well, do you know yourself well enough ?
This is like the fifth thread in which every post is "You don't know anything, this may all be an illusion." This is a gimmick answer. Using this answer, more specifically using this answer as your ONLY answer, completely undermines any sort of knowledge gained by humanity. It's a fun little paradox, but it gets old, doesn't it? I mean, if you really think about it, yourself, being your life or consciousness, is so minuscule in comparison to every other thing imaginable. Life is a tiny, almost unnoticeable flash in a larger timescale, no?
