I'm making the claim that there exists no evidence to support any of the hypotheses regarding a mind separated from the brain. You can mould your hypotheses to suit scientific understanding and that's how you get to Castiel's "hundreds, if not thousands of differing hypotheses", which is fine, if you like imaginary exercises, philosophy etc. I honestly have no problem with that but I cannot consider them valid until they are backed up with proof.
I'm not the one making the extraordinary claims, I don't contemplate the supernatural, I don't pretend to have a higher understanding of consciousness. What i say couldn't be clearer: what we can observe, directly or indirectly, is sufficient to provide answers. There's no need to add anything, which is why the default rational stance at this point should be: we are forms of life, one the results of bilions of years of evolution and, under the pressure of natural selection, we randomly adapted in such a way that we developed consciousness. Anything added after that has no evidence at its foundation, making it an ultimately invalid position. In other words, you're making it up and I'm not taking your word for it.
You didn't answer my question. Can you give me an example of what would be sufficient proof?
