But the real problem with the idea that Judaism contributed monotheism to the world is that this is hardly something to be proud of.   From an ethical perspective, monotheism was arguably one of the worst ideas in human  history.
     Monotheism did little to improve the moral standards of humans - do you really think Muslims are inherently more ethical than Hindus just because Muslims believe in a single god while Hindus believe in many gods?  Were Christian conquistadores more ethical than pagan Native American tribes?  What monotheism undoubtedly did was to make many people far more intolerant than before, thereby contributing to the spread of religious persecutions and holy wars.
