But what would distinguish a god from a sacred or divine object? Generally, a god is just a grander version of a human being.
Take prayer: the whole concept of prayer is based on the idea of talking to gods like human beings.
I found informative the Buddhist practice of prayer flags. They are put into a windy place, until they gradually dissolve in the elements, and so the good intentions put into them will disperse and go throughout the universe.
Similarly, prayer can be offering up truth, intention, feeling, into the universe in total and/or the depths of your own being.
I'm not sure, actually. It varies from person to person, and the entire concept of 'God' is quite different in monistic or Vedanti c schools than from the west. For me personally it is the underlying energy flowing through all form, and the Primal Cause which is beyond all form, time and space. I don't see any anthropomorphism there. I think that calling it God came about from western their lens, and not having a very good word for it, so they gave it the God label. Many Indian scholars would probably declare Brahman as an untranslatable concept, so 'God' wouldn't be their choice.
While to be honest the God word doesn't really occur to me much within myself anymore, I think that it makes that plenty of people, unrealised and realised alike, have chosen to use the word God in English as they would others in Sanskrit and Indian languages, because it's showing people that it's the same transcendent-immanent that people are to relate to.
Even Gurudeva did it, it seems! Talked about God to people who would understand best with that word.
