Head for a better world

Since the beginning of mankind, men have believed in gods and super-natural forces.Cavemen understandingly relied on religion to explain 'strange' natural events they did not understad and believed to be the consequences of their actions and therefore sacrificed animals and human beings in attempt to get the gods to ease up on themselves.However, since the middle ages men have irracionaly fought for their religions murdering innocent children and women, destroying vital crops , and more recently blowing themselves up in any crowded place.Such men call themselves heroes or martyrs ,fighting a so called 'holy war'.


Wars have been waged against entire countries crowded with 'infidels currupting' our world,....
but why?



After a considerable amount of time examining all aspects and reasons to: why more and more people seek guidance from priests , go to church (p.e.), are willing to believe in gods and super-natural forces (never scientifically proven to exist)and be killed while fighting for their cause ....and i have come up with 4 possible reasons:


-Sellfishness: The reason i believe to be the most common is wanting a reward for 'good behaviour' ,either spreading god's will, cleansing the world from infidels or simply living one's life following some principals.The rewards for living such shallow lives can be 72 virgins , an eternity in paradise or reencarnating as a more powerful,wealthy, and happy person on another life (Islam,Christianism,Hinduhism).


-Irracionality :How can someone believe in a god with no proof of his existance?Unortunately , many religions are proud of such an accomplishment;blindly believing in a god without bulletproof evidence that he exist, relying simply on interpretations of events that could be just as easily seen as a coincidences, claiming that if 'his miracles were flashy, there would be no need for faith' ,this is madness ,not faith , nothing but pure irracionality.


-Need:Most people seek guidance mostly because they need their life to make sense.Having in mind the great majority has a dull life ,they desperately need something to 'keep them going'.This point of view is actually the most common amongst philosophers.According with what Immanuel Kant ,a brilliant philosopher from the 18th century, stated in Critique of Practical Reason ,leading a virtuous life cannot be harmonised with a happy one ,therefore there must be a god and an afterlife so whoever lives virtuously in this life may be rewarded in their afterlife.
However, this doesn't mean there is a god ,just that it would be fair if there was one.Some people can't stand the idea that they will not be rewarded for a saintlike life so they choose to believe in something greater than themselves.



-Lack of thought on the subject:Since most children are raised to believe in a certain god and follow certain rules ,which happen to be their parents' most of the times,they do not question these rules because either they don't require much effort to obey or they are the same as their own.
