If One Person can do it... Well, I would not put it like that exactly. It is more of an expression of human existence. A natural means of dealing with the immediate environment and possible otherness beyond our sense of selfhood.
‘Substance’? I stories have a certain impetus/‘substance’ to them. If you are trying for some kind of dualism I simply do not go into that any more as the phenomenological view on that suffices - as in I don’t care much about ‘the material’ nature of nature just the human lived experience (in the sense of religious practices and the general weltenschuuang).
As with stories, cultures and traditions, they chop and change over time. If there was some ‘god’ within this that I wished to put a label on it would to attempt to suggest to you that the ‘god’ you seem only able to vaguely define is more or less nothing more than the process of spontaneously creating narratives to map onto the world and said narratives affect through feedback.
That is why I view what you seem to call ‘god’ as the communication between sacred and profane (not that there is a real delineation between the two as humans implant some degree of ‘sacred’ upon every experience they have that moves them - and everything ‘moves’ us in some way.
A guy called Derren Brown refers to certain actions we make as ‘pantomimes’. One example he gave was if you walk down a street and realise you forgot something you articulate it by gesticulation or saying something out loud before turning around and walking back in the direction you’ve just come from. You will also act out such .pantomimes when alone. This is a step towards the ‘sacred’.
For a more obvious set of examples … birthdays, your bedroom, a classroom, a necklace and such. All have haboured within them memories and meanings that make mere places/items have more meaning beyond the ‘profane’.
Note: when I talk about ‘communicating’ between profane and sacred I don’t mean this literally. It is just an abstract way of expressing this. I’m not a dualist in this sense of the discussion because I’m coming at it from a phenomenological perspective.
