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.

    It doesn’t include “perception of our own thoughts” because they’re not a thing to witness like a smell or visuals. You manufacture them immediately yourself, you don’t observe them. That’s Descartes entire point.
