Consciousness exists. This implies that either consciousness is some emergent property of sufficiently complex interconnected systems, or it's some universal force that complex interconnected systems "channel".
If it's emergent, it seems less presumptuous to assume that the most complex interconnected system of all, the universe itself, would develop consciousness. That universal consciousness might as well be called "God". If it's a universal force, it might as well be called "God". Anyway you slice it, a universal consciousness seems inevitable from a sober metaphysical analysis.
Lots of people have ascribed lots of culturally specific attributes to the universal consciousness which are obviously quite silly. The core statement that "I am that 'I am'" is really the only meaningful attribute we can identify.
