Maybe what the ancients believed was god was really spiritually advanced beings teaching us how to do the same, but as priests or disseminators of truth typically do they fuck up the knowledge and thus use it for control. Hell is made up. If anything if you dont improve your spirit you will just reincarnate here or on a similar spiritual planet, or you will go to a more advanced spiritual planet. Satan isnt real either it is just that which is negative within every atom, and manifests in 98% of people with indecisive action or drifting through life being controlled by people with 2% of decisive action.
