Materialists/physicalists seem to think you should only believe something that's provable. This limits belief to the subset of the physical universe provable by the scientific method.
An example of something not provable but worthy of belief: You meet someone you think you will become lifelong friends with. Certainly there is no scientific proof involved; merely intuition. It's OK to believe you might become lifelong friends with them.
What about scientific speculation; for example, multiple universes? Why do scientists even think about such things if they can't find a way to prove them? It's because they believe they could be true with no evidence they are true.
The existence of the subjective experience of consciousness deviates from the scope of provable science enough to warrant believing it is outside the physical domain. After all, all other emergent properties (such as the surface tension of water) are still physical, having atoms obeying the laws of physics. Yet there is no quantum field called "consciousness", so it may not be physical in essence.
