If you have faith in a 3rd-person god, then let's test that faith. How do you know this god exists if it's somehow outside of you and you can't consciously detect it? The only kind of consciousness that I know exists for sure is my own, see: philosophical zombies.
What do you mean by a "3rd-person" god? Monotheistic gods, such as the Christian god, do not seem to be 3rd-person gods. "I am who am" in the Bible was God's definition of himself. Are you referring to polytheistic gods?
But the monotheistic Christian god almost always seems to be referred to as a "He" rather than "I". That seems confusing to me, and the above discussion about whether or not god is our own consciousness, doesn't help in that regard.
It can be extremely confusing. These types of debates often go round and round because people typically aren't aware of when they shift the vantage point from where they attempt to base their argument.
There are two fundamental vantage points that one can take when attempting to discuss god: 1) from a lower vantage point, and 2) from a higher vantage point. Speaking from a lower vantage point is like trying to talk about 4-dimensional spacetime from our 3rd-dimensional frame of reference through inference. Speaking from a higher vantage point is like drawing a tesseract on a 2-dimensional plane and deducing its properties. When speaking from a lower vantage point, infinite regressions result because of irreconcilable paradoxes. When speaking from a higher vantage point, paradoxes become self-resolving.
