This is true of any phenomenon. The fact that phenomenon X is unobservable doesn't discount its existence. But it doesn't give us reason to think it exists either, does it? I don't know about you, but to believe that something exists I need more than "I can't demonstrate with certainty that it doesn't".
What reason do you have to believe that a phenomenon fitting the description "consciousness" exists in all things? Is it simply extrapolation from things that we have good reason to believe are conscious and which we have good reason to believe are made of the same stuff as things that are not noticeably so? In other words, does the argument essentially go: "I am conscious. I am made from atoms. Rocks are made from atoms. Therefore rocks are conscious."?
To me the two most obvious ways of accounting for phenomenal experience is that it's somehow reducible to fundamental material stuff, or it's fundamental itself. The other option I personally think is a strong contender is that our evolved-for-utility ways of observing, thinking about and modelling the world in such ways as these doesn't get to what the actual nature of what we're modelling is like. (The contents of experience might tell us more about us, than about the world beyond us).
The problem for monist substance materialism, as described by physics, is that it appears to have no in principle way of accounting for experience. That's why we can't just assume it will some day account for it. ( There's no place for experience in the current physical model of what exists). And the scientific toolkit which helped us come up with a physical way of modeling what exists and how it works, doesn't seem equipped to find a way of modelling experience in those terms. Experience is apparently unobservable and unmeasurable and can't be verified inter-subjectively, because it has radically different types of properties. (Hence talk of The Hard Problem). We might one day be able to explain experience in physical terms, but no-one knows how that could happen, except in the form of broad speculative hypotheses.
That's why some people reasonably posit experience might not ultimately be explainable in physical terms, and might be a different type of substance, rather than a property of material substance. Evidence like neural correlation suggests that if experience is a different fundamental substance, it is closely linked/intwined/integrated with material stuff. (Rather than a fundamental substance capable of floating about independantly as traditional spirit/soul type notions of substance dualism based in religious/Cartesian thinking suggests). There are different types of panpsychism which speculate about how that material-experiential type of relationship works (aka 'mind-body' relationship). Some suggest rocks have mental experience, some suggest they don't.
Potentially the most promising work being done on mental experience is IIT, which is trying to come up with ways of quantifying and predicting experience by looking at how brains work (it's led by two neuroscientists). They say their attempt at a science of experience implies panpsychism is true.
Who knows. (Nobody). But panpsychism is a serious contender.
