Is the Jewish religion older than the Zoroastrian religion?

It is difficult to say. Judaism was heavily influenced by Zoroastrianism and the concept of final judgment, heaven and hell, the arch-angels, the concept of an ethnical-uiversal God as opposed to a tribal one came from Zoroastrianism.
The general concensus on Zoroastrianism presently is that it is between 3,300 and 3,400 years old. Some say 3,700 but that is unlikely. Most scholars believe on 3,000-3,500 range.
These dates are based on linguistic evidence and archeology and not the usual Greek anachronism which often corrupts historical fact.
Judaism on the other hand goes back to Moses and not Abraham so around 3,300-3,400 years at the most. It is possible that they are contemporary. Answer: Zoroastrianism and Vedic Hinduism are contemporaries and among the oldest organised religious systems on earth.

  • Answer:
The date of what time Zoroaster lived and when the Old Avestan Gathas were composed cannot be declared with certainty. Commonly quoted dates are: either around 600 BCE, or at an undetermined time in the second millennium BCE.
Judaism was founded by Abraham shortly after his birth in 1812 BCE.
Judaism borrowed nothing from Zoroastrianism. Any similarities are because certain basic concepts go back to the original Noahide teachings.
The dualism in Zoroastrianism is repudiated repeatedly in the Talmud.

Since the two groups lived side by side in Babylonia, there may have been some borrowing in language or other minor matters. But in terms of beliefs, the two are quite different.Judaism, according to tradition, has always been monotheistic. Even at the height of the unfortunate spread of idolatry among the less-loyal Ten Tribes, there were thousands who remained loyal to God (1 Kings 19:18).

The Zoroastrians, however, believed in two gods, not one. The Jewish Sages who collated the Talmud in the early centuries of the Common Era lived in Babylonia, witnessed the practices of the Zoroastrians, and recorded this fact (Talmud, Sanhedrin 39a). In addition, Zoroastrianism is unlike Judaism in that:

  • its deity is not immanent
  • it believes in worship through intermediaries, who are themselves "worthy of worship"
  • evil has its own creator, Angra Mainyu or Ahriman, which had always existed
  • some of its adherents believe in a self-creating universe
  • some modern scholars see it as a form of pantheism
  • it has "fire-temples," with worship in the presence of flame
  • its adherents are not required to marry within their faith
  • some Zoroastrians dispose of their dead through ritual exposure to the open sky, while some others cremate the dead
  • dogs are considered sacred
  • such creatures as snakes, ants and flies were "not created by the creator of good"
  • it includes a virgin birth, in which its messiah will be conceived without sexual penetration.
