>So how does materialists explain consciousness and how are their believes unprovable?
No one can. Even religious “explanations” such as a “soul” just kicks the can down the road. A “soul” is then just a different kind of thing, to which we can then ask “how do souls work? What lets them give rise to subjective experience.”. It’s no more an explanation than giving the answer of: “stuff, because reasons”.
The hard part of the hard question is that we don’t as of yet even have an idea how to really formulate the question. We don’t yet even know what answer would even look like.
