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.
