Lets not forget that most brain development is at a very young age. If you are pounding religion and supernatural into their heads as young children, and always praying and or talking about religion. The child will have that almost implanted into his mind as to what is real and what is not. We take in many things as a child, that is how we interact with the world, that is when we do our learning. A human child is a fragile and delicate creature and must be nurtured much longer than most species. That is why our brain development is so high, we do not have the innate ability to walk, crawl, or interact with people these are all learned traits, to the best of my knowledge. So at the same time you teach walking, if you are programming their brain to think that ghosts and walking on water, and divine healing are real... well guess what the poor child's reality will be based on things that are not REAL. Which has a horrible effect on their lives if they are to live a reality based life, because that would be going against the most basics things that were taught to them as a child. Ever wonder why bigots breed bigots, stupid breeds stupid? Parents, a whole lots of shitty ones out there.
