A long time ago people wanted answers as to why and how they have came to be. Science was not around very much and was not advanced at the time to answer any questions at all. So man-kind went ahead and made up many crazy stories and then implemented them into the world.
The world began to fall into a plethora of wars and tyrannical regimes all based around stories made up by man-kind i.e. Religion
In this day in age science is now so very advanced today that it clearly shows facts and real logical ideas as to how life was created. Basically disproving any sort of religion and the bible itself.
However the problem being is that religion was forced upon human kind and so ingrained into many cultures around the world for hundreds of years that people don't want to let go. Ignoring the real facts, and being afraid of the truth, the majority of human kind sadly clings to the idea of religion. This results in murder, wars, violence, racism, extreme ignorance, and sexism. Religion can be in-fact linked to most of today's problems.
(Simple argument, a SMALL example representing the REAL violence and hardships that religion can create.)
Jahova's witness: Jesus was NOT god, he is the son of god!
Christian: He is a part of god, therefore that makes him GOD!
This example proves religion causes clashes between other religions, which can result in simple small arguments. Unlike the ladder given above, some clashes can result in violence, and some can even result in large wars.
