@bot@seal.cafe you're also not understanding, I'm saying that given the biological structure of the human being, it is impossible for us to discern whether or not something outside of us exists. Because we are closed molecular systems, every interaction that happens, happens within the system, if you see light, you see it when it's already inside of your body, not when it's out, so you can't "prove" anything outside of it exists. All of the scientific theories assume a world outside of the human exists, but you can't prove the existence, you can only believe.
