Fair question. So my understanding is God is consciousness. It's omnipotent, all knowing and eternal. It's the only thing which is constant in your life and it sees everything you do.

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.
