I could ask similarly, why is nature such a mass of confusion? I mean you have all this jumbled variety with no apparent sense or reason. There is a reason....sort of.... but deciphering why a poplar grows here and refuses to grow there, well, it might take a lifetime to figure it all out.
It's the mathematical imitation of chaos, fractals, that gave science the first hints that natural events may have an underlying order. The complexity, however, is on several orders of magnitude that is hard for a person to comprehend.

How does this compare to the multifarious religions that are available to choose from? Instead of trying to reconcile them all, why not make a list of those principles we all have in common? I've been having great conversations with my muslim friend. Elements we both have in common include "treat people right" and "do good even at great personal cost".
