Can you show me somewhere that these results you are talking about are exactly the same every time?
And you can't prove that you are consious either. If it is material proof you seek then you will not find it because obviously consiousness is pretty immaterial. Just think of ur dreams. If you consider immaterial proof to be valid then you can get some in dreams or by other means. You can't record this however and show everybody a video or something so that's kinda troublesome.
