An atheist knows that the fundamental reason the human species has survived is the beneficical nature of altruistic behavior. Development of cooperative human endeavors has built the necessary infrastructure for humanity to survivie and not drown in a toxic pool off it's own waste.
Superstitious religious ####, in this day and age, are simply those who cannot or will not learn what interdependent humanity means, who prefer to think their privilege relative to other humans in the world, has a divine origin, or who, for purely selfish reasons, wish to believe their life is more important than other forms of life, and granted by god the right to abuse those other forms by pollution and waste, without accepting responsibilty for their own actions.
There will always be big mysteries, but they are not about abortion, war, oil, money, churches, or governments.
Anytime god is invoked in those argurments, it is a lie.
