No, probably Zoroastrianism.
There is evidence that the roots of Zoroastrianism go back to the second millennium BCE, but the first mention of it in literature, with the trappings of religion, was around 500BCE.
This synchronizes rather closely with the first mention of Judaism in literature. Of course, the Jews were a literate people long ago, and could have written holy manuscripts as easily as the Zoroastrians.
I think we'll just have to say that both of these religions are ancient, and given the culture of the era, we probably may never be able to be more precise.
Of course, the Jewish people and their religion are constantly in the headlines today. The animosity toward them in medieval Europe, culminating in the Holocaust, is rather difficult to ignore, much less forget.
Even today, in the supposedly "modern, civilized" United States, anti-Semitism continues to be the most widespread form of ethnic hatred: more than African-Americans, more than Latin Americans, more than Muslims, more than any of the "Oriental" cultures.
Probably even more than women, although I haven't come across any statistics to support that.
