When you call him a "mystery god", are you implying that god doesnt exist or you just dont know ????
Technically nobody knows.
Religion is pretty antiquated at this point in time, but survives due to its captivating mythology and communal element, and the fact that most of The Earth is poor and uneducated. It was the best explanation that our brightest minds could conceive of before science. If there is a higher power, my guess would be it has no relation to our very myopic and human-centric religious texts.
The moral aspect is fine, but that's always existed alongside and often separate from religion. You don't need to believe in things for which there's no proof to be a good person.
