Here's how. The exceptional person can be strong but a group of average people can be even stronger. Here is the problem, it's hard to have a room full of ducks to say quack at the same time. Meaning that it's hard for people to get along and agree on subjects.
So. How do you get people to get along? Simple! Make them loyal to an unquestionable force that fills them with fear/hope/anger! Simple eh? By doing this they solved alot of problems like; who created the sun? God! Who controls the waters? Neptune! And so on and so on...
This shot of higher than anything, suddenly we had emperors that can talk to god and do his bidding. With that done and said I can safely say that religion has dome some good for humanity as far as devolving our societies. A lot of famous inventors, philosophers, and scientist where very religious. For example, Charles Darwin the man behind Darwinism was a priest and when he found out the startling information he could not cope with it for a while.
We can all agree that killing people is bad right? That is due to our higher form of intelligence and reasoning. A fish's memory only lasts thirty seconds; a dog can only recognize twelve words, and so on and so on.
Now don't take as a sadist or any thing of that nature, I'm not here to say that there is no higher power. All I'm questioning is the blind devotion to an unseen force that only a select few can communicate with. That is all.
