How are Dark Mtter and Consciousness different from Spirit?

[Rhondazvous]

PS:

I'm not trying to be difficult or argumentative, I genuinely have no conception of how something can exist yet be non-physical

Of course, that doesn't mean it's impossible. That would be an argument from incredulity. But to suppose something non-physical as an explanation would appear to require exhausting all physical explanations there could ever be. How could this be done?

Has anything non-physical ever been observed  to exist? If not, how can it even be suggested as an explanation? Of course, it could be physical, but just behave very differently to the physical stuff we're used to.

Or like... anti matter or something? My science isn't so good at this stage

You're doing a good job, rob (rhyme not intended). This kind of dialogue will help us get to the bottom of the question without fiat credulity.

To proceed.

If you hypothesize that there is some kind of matter which is there but undetectable, how can you ever exhaust physical possibilities? You have made your argument unfalsifiable. You are also engaging in special pleading when you demand that spirit be something that we have experienced but do not make that same demand on dark matter.
