Which Religion Is Older: Hinduism Or Zoroastrianism?

please provide dates and references

Hinduism, easily. It dates back to no later than the 3rd millennium B.C.

Zoroastrianism is said to have originated sometime in the 8Th or 7Th century B.C. That's when Zaruthustra is said to have lived.

Hard question, given that "Hinduism" is such a diverse range of traditions, dating over many centuries. Indeed, many scholars have argued that Hinduism did not exist as a religious identity until the period of British colonization, but rather it was a wide range of Indian popular religious movements. Nevertheless, Zoroaster (Zarathustra), the founder of Zoroastrianism, probably lived in the 6Th century BCE, which would place him firmly in the Axial Age of world religions. Some scholars favor an earlier or a later date. The earliest texts of Hinduism which are still read - the Vedic texts - date from about 1500 to 1000 BCE. So arguably Hinduism is older. But some scholars would argue for a very early date for Zoroaster, and ancient Iranian religion certainly predates the 6Th century BCE. So it all depends on your definition.

Every time I see this question I get more data affirming one is older than the other.

They're both hundreds of years older than sanity.
I sometimes wonder if they weren't 'linked' at one time.
I have nothing to back that up.
Both fascinate me.

Both are so much richer on every level than the cheap sentimentality of Xian and muzzle which are both born, bathed and raised in FEAR and blood.

Well you got the dates and references from other answerer's i am just saying this off my observation and a teacher telling me this.

alto of Zoroastrianism (most of it actually) was from Rig Veda. They worship the Agni Deva.

Hinduism by far is the oldest religion in the world.
