Is not the purpose of evolution for a species to continue in an upward development? As a species developed would not it conquer such aberration? Thank you. This is closer to what I hoped to explore. I can only say that evolutionary theory does not carry the burden of either "intelligence" or "design." It merely is. I can believe in God and believe in evolution. (I know that isn't true for some folks.)
Species which survive DO develop various survival mechanisms. A virus runs through a population, and the survivors develop immunity, for example. Then the virus mutates and the cycle goes on.
I concur......most of those who believe in only evolution reduce the argument to psychological reductionism; people believe in God because there are benefits derived from believing. But this argument can go both ways. For it can be said that there are likewise certain benefits derived from not believing in God. Who wants to abandon personal preferences and be held accountable to an absolute moral standard for every action?
