God... Truth or fiction?

Let's start with the fact that Judaism is not the original religion of the Jews. Before Judaism, the Jews were pagans just like the surrounding tribes. The adoption of a single faith can be traced back roughly to the time of Kings David and Solomon. Regarding the preceding period, things are mentioned that contradict monotheism. For example: the quote I already cited, "Man has become like us," mentions of Abraham's sacred Grove, Moses' burning bush, and the golden calf.
So it is foolish to say that Judaism is the original faith of the Jews. They simply eradicated most of their pagan customs (but far from all).
And therefore, paganism can be viewed as a much more ancient religion.
As for the non-violence of the Orthodox Church. Read the history of Siberia during the period of the late 19th and early 20th centuries. There was such forced conversion of indigenous peoples to Orthodoxy. And what about the struggle against the Old Believers? And the intolerance toward other religions?
