There is nothing misguided here on my side.
Oh boy.
Let me teach you about the burden of proof. It was formulated by a guy named Bertrand Russel. He was a mathematician and a philosopher.
The burden of proof is something that is borne by someone making a claim.
What is asserted without evidence, can be dismissed without evidence.
The claim that consciousness, something that has only been observed and studied within the physical universe, could exist without a physical substrate wherein it occurs, is white an extraordinary claim, and is not supported by any evidence. As such, it can be dismissed without evidence.
On the other hand, there are numerous different experiments that show that consciousness does not occur without physical processes. Which is not extraordinary at all. (Cybernetics, for example, is about the study and design of systems that direct themselves.) So there is plenty of experimental evidence that suggests that consciousness not only occurs withing the physical universe (and it has never been observed outside of it), but could not exist without it.
In Science you have to give evidence
It's science, not Science, and you can read up on the evidence. I provided a few pointers. Listing it all would take years.
(There are many experiments you can do at home.)
