Human race's need for religions

From the beginning of the human race there was a need to warship a, sometimes multiple, supernatural deities calling them gods and
giving them divine powers and judgement over humanity.

This need for those supernatural and sometimes beastly beings came from the fear 
of death,
the fear of the unknown; who created us, how did we came to be, et cetera.
If you look closely at every religion there are some great similarities 
that almost make them same yet they appear so much different because of their followers.

In every single one of those religions there is life after death in various forms in order to remove the fear of death from humans, because we can not comprehend that 
after we die we simply seize to exist.
Another similarity is the existence of an all-powerful being who is good and 
caring and a second one who is a malevolent force with an atrocious appearance.

These two opposite beings have their role to play; the first is all good and kind and
is what turns us good just by following rules that either he or his prophets have given us
and the second, the malevolent one, is responsible for every bad thing we do and is attributed our every evil action, blaming them to a darkness he infects us with, taking the burden of responsibility off of us.

In the beginning all religions were created to satisfy the need of humanity to believe 
in something greater than themselves, but people started getting greedy and 
ruthless so they used religion to manipulate the masses in order to achieve their own personal 
goals, be them political or territorial, the Holy Crusades for example.


Finally in our days there are over 5000 active religions and the need of the human race 
for inventing or following religions still goes on.
