I don't think there has been a time in the last 200 years when man has not been killing man and during the 18th and 19th centuries, there was far more belief in god but just as much slaughter. They believed more that we do today yet they still fought and killed each other in ever increasing numbers.
When we got towards the end of the 19th century war became much more industrialised leading to the dreadful slaughter in the American Civil War in the 1860's and then the even worse slaughter of World War 1, still all sides said god was on there side and still the slaughter went on culminating in the second world war which led to even greater slaughter and the dropping of 2 nuclear weapons on Japan.
We had to drop those bombs to prevent an even greater loss of life and for those 50 odd years of the cold war and the tight rope we walked, the bomb helped prevent a third and probably final global conflict.
I don't think we are anymore uncertain about our future than our ancestors were, we have more to fear, if we let fear rule our lives that is, because we are better educated and far more knowledgable than our forbears but I don't think any ancient evil gods are going to pop out of the woodwork and lead us to armageddon.
We are inventive, clever, resourceful and we have an infinite capacity to learn and change, what ever the world may face, I am sure we will survive for a while yet at least I hope we will!
