AB,
There are no materialistic explanations for conscious self awareness.
Yes there are. Stop lying about that. Which (if any) of them will turn out to be correct is currently unknown however. That though tells you nothing whatsoever about whether any possible materialistic explanation would be "totally impossible", which is your claim.
The term, "emergent property" is just a meaningless label which offers no explanation for what comprises conscious awareness is or how it works.
Of course “emergent property” isn’t just a meaningless label. It’s a well-understood and widely documented phenomenon.
You can try as you might to define a single entity of awareness from discrete material reactions, but such effort will be doomed to failure because awareness requires perception of material reactions - not the reactions alone.
Your ignorance of the nature of emergent properties is letting you down again here. You can try to “define” a single entity of water from lots of hydrogen and oxygen atoms too, but you’ll never find it.
The bottom line is that you need more than material reactions to perceive material reactions.
That’s not the “bottom line" at all – it’s just an un-argued and un-evidenced blind faith claim.
You need the human soul which is not of this material universe but can perceive and interact with this universe through the window of the human mind.
“It’s magic innit” isn’t an explanation for anything. It's also all you have.
