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.

    Most scientific claims are based on probabilities, not certainty.

    E.g…

    • We’re 95% sure this psychological phenomenon happens in this scenario, and not randomly.
    • We’re 99% sure that this drug works, and it’s not due to random chance.

    Proof is about probabilities.

    How likely is it that the mirror turns black vs. continues to be a mirror? How likely is it that a person continues to exist when you can’t hear them?

    Especially considering that you continue to exist when someone else can’t hear you.

    You don’t need to be 100% certain. Just go for Occam’s razor.
