To answer the question of why humans give name to God. It's to make god more relatable so that they can workshop it. And use devotion to come closer with it. Look up Bhakti Yoga.
Now, you cannot worship consciousness as humans because it's invisible and you can never imagine it. You need a version of consciousness that you can see as well as you can relate to. So cultures invent localized version of God which people can relate to. And of course it will have attributes similar to that of the culture. But the properties kind of still hold. Like all knowing, powerful etc.
I've always thought arguments like these are unnecessarily applying a term loaded with human conceptions and biases in a way that doesn't shed any further light on the thing it's applied to. Like, what do we gain by defining "God" as consciousness? Why can't we just say "consciousness"? And is it worth the added confusion that when we say "God", we now don't mean what most people think "God" is?
The only reason I can come up with to do this is discomfort at saying, "I don't believe in God."
