What is so mysterious about human consciousness?

[Shankapotomus]

36. You are correct about I am saying

That the self is attached to the particular atoms that compose the brain.

You can't have consciousness without the material to support it just as you can't use software without the device to run it on. But the mere fact that any two consciousnesses exist on separate "machines" guarantees there can not exist "copies". In that respect, consciousness is NOT like computer software.

Consciousness has to have a material host, afaict.

But it IS like software in this respect:

Since matter cannot be created nor destroyed, only change it's form, it perhaps follows that the atoms that now host your consciousness will be reused, given enough time, to host the consciousness of another entity. And although, you will have no recollection of yourself or your past lives, because an individual consciousness' unique identity is probably connected to a single constituent atom, it still will be YOU who doing the feeling and experiencing for that new entity.

At least that's my take on it.
