Samson a religion that has more common ground to reality would cease to be a religion. I think you need the supernatural in religion and that is its general appeal to the populace. The idea of living forever in eternal bliss, engulfed in the presence of god, angels, and other supernatural creatures, never being sick, and living in a place where death is no more is what holds religion together. All your worries and fears of this life in the real world would be a thing of the past.
There is nothing people will not maintain when they are slaves to superstition
