You forget, people in the US have no Idea what Zoroastrianism is, we think of some ancient paganism back to the time of Alexander or Cyrus or something...
I still dont get it, I wonder just what Zoroaster had to do with the religion named after him!
It is a very ancient religion and both Christianity and Judism are said to be based on it. It was the first religion to recognize One God. The Magi were from Persia, home of the Zoasters. The similarities between the astounding. It IS from the time of Cyrus (and before). As you know, Cyrus is mentioned quite favorably in the Bible as the friend and savior of the Jewish people. He rescued them and kept them safe.
Zoroastrianism is all about GOOD WORDS, GOOD THOUGHTS and GOOD DEEDS - Monotheistic religion. Way before the popular religions of today - in fact most of the relgiions piggybacked off of Zoroastrianism.
