There are so many religions, each one has its personal experiences and sightings that lets the devout know they are following the one true religion, each religion claims their holy doctrines are divine knowledge and all others are worshiping man made religion or are misguided. we, as a people cannot distinguish divine knowledge from man made religion. Isn't it suspicious that we cant make a distinction between the unearthly word of all knowing,all powerful god, and man made books. You'd think the real one would be more obvious to everyone. this implies to some degree, that all religion is man made.
