I concur with those who ask for clarification of terms, first and foremost. Especially the value determination of something being 'better', as
@Silmarien mentioned.
To investigate the question though, we are assuming a bit here, aren't we? You are assuming that the Material exists, or could exist, in some extra-personal sense. Do we not though, conceive of everything through our person? That we 'see' something only occurs when consciously aware thereof. While hypothetically the eye picks up light from various objects, we only see what our consciousness, our personhood, lights upon. From the notion that there is something beyond what we are consciously aware of, we assume that we are in fact observing something with a reality external to our observation thereof - but is this necessarily valid? It is how much anthropic principle you would apply.
So we humans can only know of something, or affirm it, if we or intersubjectively by abstraction, could become aware of it. So only by awareness by someone, did we actually bring something into actuality. The concept of a 'continent' didn't exist until articulated, and the Americas did not exist to Europeans until perceived, seen, and thought of.
So you are assuming something never placed in relation to a conscious awareness could exist. On what do you base this claim? Deductive reasoning from human experience certainly doesn't support this, as something in a sense only exists once perceived.
Or do you assume things become existent once perceived, but did not exist prior to it? Or are we dealing with potentialities? That Schrodinger's Cat is both alive and dead until the box is opened?
For us to blithely assume that our observable world reflects something that exists extra-personally to ourselves, requires many metaphysical assumptioms. Based on human experience though, the unobserved is in some sense also the non-existent.
God as the Ground of Being, I AM that I AM, that which fundamentally exists, requires that it be observed perhaps. A personal God as in a Being, makes far more sense from the grounds of human perception and experience, than essentially claiming non-existence becomes existent, as lesser creatures become aware. This is fundamentally related to what
@Dirk1540 was saying.
CS Lewis is a good source here. In Pilgrim's Regress, John falls in with a bunch of Idealists. The principle of a holistic everything as God, however belies how a portion thereof stands in relation to the whole. An 'I' as part and parcell of a pantheistic entity, is still in some sense separate, and thus still implies an extraneous Him. It is a matter of perspective, perhaps.
If we construct what we deem 'Reality' by conscious thought, that Reality, by nature, remains dependant on Consciousness. As we cannot affirm our experience beyond our conscious experience, we are stuck with conceiving everything necessarily from an aspect of Mind. It is not coincidence that Neoplatonism, Buddhism, Confucianism, right down to modern Quantum Physics and Relativity Theory, require a fairly stubborn idea of Consciousness being required to bring Actuality and determinability. This is why Existence itself, even in Pantheistic systems, becomes linked to aspects of a Mind - in essence therefore hard to distinguish from an ineffable Person.
