Only if you believe centuries of propaganda. For nearly two thousand years, the belief in only one god—monotheism—has had a monopoly on western civilization. That means that monotheists have been teaching about religion from a monotheist perspective, which is naturally biased in favor of monotheism. Monotheism’s triumph in the west was not due to its inherent superiority, its fundamental reasonable-ness, or its unique appeal to human beings. Monotheism triumphed over polytheism because of economics, war and politics. To modern western people, monotheism seems like the only reasonable option because monotheists have been saying it is for ages. It seems like the only reasonable option because for most people it has been the only practical option. But none of this has anything to do with whether it is actually a better option. If you say “polytheism is ridiculous” over and over again, people will believe it is true because they have heard it, they are used to hearing it, and more importantly, because nobody has been able to present the opposing viewpoint. There have been basically no polytheists around to counter monotheism’s distorted caricature of polytheism, so people have naturally accepted the only point of view that they have heard. Eventually, it has become something we all just assume to be true. But it is not.
