This is so on the money. We have a vocab and conceptual framework for tech but not for 'spiritual explanations'. What I call the metaphysical, to distinguish from the physical, is too complex and messy, and is rarely collectively and consensually experienced. So then only rules we have are 'spiritual' - as in religious or psychic. We are only beginning to grapple with the 'spiritual' in a scientific way, and even so we are a long long way from developing the means to comfortably discuss the 'spiritual' side of ET in a wider cultural frame. This is our materialistic conditioning speaking loudly to us. We must struggle to develop the means to think and talk in 'spiritual' or metaphysical terms, and that means ignoring the doubters and deniers who will ridicule and jeer.
