How can I prove that everything I see really exists and isn’t just an illusion/ image created by my brain? How can I really know that once I look away from something that it is still there and doesn’t turn black? I thought about the mirror, but maybe the image in the mirror is also just created. The people I hear talking behind me could also be gone but I only hear the audio and once I turn around they appear visually. I thought about using a camera but the content that is saved on the camera could also be fake.

Can someone tell me how to prove that others really exist?

How can I really know that people are responding to this question and not only AI? I have absolutely no proof that this forum could be real. Look at ChatGPT.

I have so many questions.

    Read some complex scientific stuff, e.g. physics. Try to really really understand the formulas AND the meaning behind it. Ask others for help and explanation if you can’t understand it yourself, but don’t give up until you got it thoroughly.

    Then ask yourself if you (your brain) would have been able to produce this.

    No? Then there must be someone with a bigger brain than yours.

    Do the same with some truly creative art.

    Or watch some really amusing comedy live show.

    Or a circus.

    Or…

      Just the complexity of all the things that happen in the world and individual lives when I’m not looking is enough to do that for me. Like, if I smashed in the door of any random house I would find new and different furniture and random strangers doing whatever it is they’re doing at that time of day because everybody is living individual lives. Sure, I could be hallucinating that too, but really I do not think I am creative enough. I’ve also worked in multiple positions that had more opportunity than most to peer behind the curtains into people’s private lives to the point where I easily accept that life is happening all over the place.

      The shared simulation is much more plausible to me than me existing in an individual universe. I don’t really think it’s true either but that’s more of a bias.
