A century ago, it was relativity easy for men like Friedrich Nietzsche, Bertrand Russell, and Jean-Paul Sartre to make bombastic statements that God didn't exist. They spouted off unsubstantiated claims such as 'God is dead' and religion is the cause of all mankind's' problems and millions of people bought into this lie. It helped spawn the existentialist movement, Nihilism, and became the theological backbone for evolutionary science. Atheism shrouded itself in the cloak of academia and science, and definitively helped make the 20th century the bloodiest on record.
