THIS IS JUST MY OPINION...not to be takin` seriously at all...
One day a bunch of pretty smart people if you ask me, had sat around eating food & drinking wine discussing many things. One being the with the realization that the vast majority of the average folk who were confused with the question.."How did we get here"......These people wrote a book in which everything could intertwine and relate to in some area of the book or another & in one way or another. This was something to fall back onto when confused or feeling lost with ones self and many other things. I've discussed this very briefly with friends & we agree that religion was a pretty genius way of keeping people in check and far from being lost & or the feeling of being very alone. Pretty cool I think...simple & just my opinion...
