On the effects of Zoroastrianism?

I have read most of the works of the real Zarathustra, known as Zoroaster. How deep is the influence of this prophet on all religions, save the Meso-Americans..Lil. Is it true like with Nietszche, that he was the first one to think that there was such thing as moral order?

Here's the awesome site.

"Is it true like with Nietszche, that he was the first one to think that there was such thing as moral order?"

I think he was the one who founded mail order. He came down from the mountain and announced sale prices!

It is the first monotheist religion. But the Avestas are not all of Zarathushtras teachings. Only the Gathas are what he wrote, the Avestas were written after him by other sources.
here is a good site on Zoroastrianism

Well I don't know who first thought about moral order but I know Plato asked the question in one of his Dialogues.What is Moral?Nietzsche was my favorite Philosopher and writer of all time .Those aphorisms were funnier than hell.He sure hated Christianity and Nationalism.You know they say Nietzsche had sex only once and contacted venereal disease.It was N.'s view that the experiences we have through life create a work of art.I just read "Beyond Good and Evil" last week again.Oh there is so much more I want to say about Nietzsche and Kierkegaard for that matter.But for your question I don't believe anyone can Gage the influence of Zoroaster on any particular religion.I honestly believe this question is open to opinion.
