Do you think if Christians/Jews/Muslims (monotheists) knew more or studied about Zoro

... then essentially, they would know more about their own religions or at least the history and influence concerning them?

Of course.
When anything at all is looked within the minuscule time line of one human life it gets completely misunderstood...

Yes, the Bible mentioned Zoroastian Priests visiting Christ in Mathew.

Zoroastrianism is Soho like centuries ago

get with the new styles man come on

During the Israelite's exile in Babylon, their early religion was heavily influenced by Zoroastrianism. After their exile they came out as Jews with all the Old Testament and their other writings. That's the long and short of it.

No, because Zorastrianism is a dualistic religion and quite different from both Christianity and Judaism. Zorastrian beliefs and practices are very different from those of the two great monotheistic religions. When one studies comparative religion, the differences are what startles one, not any of the superficial similarities.

Add Baha'i. Yes, studying the spiritual teachings/message of religion, as opposed to the man-made encrustations (another topic), we learn more about our own religion and its fundamental connection to the others.

One of the teachings of Baha'u'llah, founder of the Baha'i Faith, is that religion is essentially one, progressively revealed message for the upliftedNTnd betterment of humanity. The message consists of two parts: the eternal spiritual truths which have to do with what it means to be human and are expanded and deepened with each new outpouring from each new universal educator; and the social teachings, which are in essence the non-essentials of religion and change from age to age as humanity progresses. Man-made encrustations get added on through time as those with personal agendas seek to bend the original pure teachings to fit their ambitions. When the most recent religion reaches its darkest period, a new outpouring through a new universal educator appears upon the horizon and the process begins again.

To learn more about the connection to other religions and the progressive revelation of God, Baha'is spend as much time as possible learning about other religions, including Hinduism and Buddhism. Baha'u'llah, by the way, was related to both lines of universal educators through each of his parents, those from the Abrahamic side and those from the farther eastern side.

You are incorrect.

Christianity did NOT borrow from that religion. There have been hundreds if not thousands of religions in human history and by coincidence some may have things in common. That is all.

Certainly as it seems to have had a great influence on the Abrahamic religions and predates Christianity by as much as a thousand years.

It could be in essence was a religion from God but over thousands of years people changed it and twisted the real message ..God had send so many messengers and he informed us about almost 25 of them.. the reason for sending those messengers is that people will not have any excuse for denying His existence .

How do you know we haven't read up about it?

You're making a pretty big assumption there, aren't you now?
