Why I am an Atheist#1

Religious belief has resulted in some good things and some terrible things throughout history and still does today. I believe that the good things would have happened anyway (because lots of people are basically good and want to help each other and have the urge and talent to create wonderful art, buildings, music etc) but at least some of the terrible things wouldn't have happened. Some people of course are horrible, make bad decisions, are damaged etc with or without religion's influence and natural disasters happen (but wouldn't it be a better world if there was no blame or bullshit around natural disasters just help and support for each other?). BUT there are people who do terrible things purely because they have been brainwashed into thinking they are doing a good thing and there are terrible things that happen (routinely mutilating children, oppressing women etc) for which there would simply be no excuse without religion.
