One of my most central criticisms of Religion is that people simply don't have the knowledge it must suppose to support it claims. In other-words it seems like a bunch of people just making stuff up. So is religion just making stuff up?
*** Feel free to make arguments for subjective centered knowledge, but know that I reject all claims of "spiritual enlightenment" or the like. I find people who assume they have some type special transcend insight egotistical and smug.
People have "spiritual" experiences. Some of it's dreams some visions. People actually believe they have had a supernatural experience. I suspect a lot of people have had these types of experiences and if you haven't it'd be hard to understand the reality these experiences take on. Also I don't think they necessarily made anything up, they just maybe filled in some of the gaps. More like creating a theory based on what they experienced.
Then what happens is one group come into power and creates a ruling class. These elites have more time for abstract thinking so create stories to explain their world which includes such spiritual experiences. Since they have the power, they can enforce the acceptance of these stories which lacking any other knowledge, explain the reality the common folks experience. A national religion gets created.
These dreams/visions then have a ready explanation offered by these religious stories which reinforces the belief in the religion.
So a person may have a dream/vision/spiritual feeling which is understood according to their religious belief.
I also suspect that belief predisposes folks to these spiritual experiences. Given enough belief/faith the mind can create these types of experiences. Whereas if your a skeptic, your subconscious mind is less likely to create these spiritual experiences for you. It still may happen though. Like the Apostle Paul on the road to Damascus after such an experience was converted to Christianity, maybe brought on by his own guilt of his atrocities committed towards Christians.
Did Paul make everything up? Not entirely. He just put two and two together and created a logical understanding based on his experience and what he otherwise knew to be true.
