What Is the Oldest Religion in the World?

Long before Christianity, Islam and even many of the empires known to history, people were already erecting temples, burying the dead and seeking answers about the supernatural. That is why answering what is the oldest religion in the world may seem straightforward, yet it depends on a crucial distinction: the first religion of humankind is not necessarily the oldest religious tradition still alive today.

Is Hinduism the oldest religion in the world?

When the question concerns a major faith that remains in practice, Hinduism is often identified as the oldest religion in the world. Its origins extend back to religious traditions that emerged in South Asia more than 4,000 years ago, and it has neither one founder nor a clearly defined date of origin. The Smithsonian describes its roots as reaching back more than four millennia.

Modern Hinduism encompasses varied schools of thought, deities, philosophies and forms of worship that have accumulated over centuries. The Vedas form an essential part of this inheritance. The Rigveda, the oldest of these texts, is generally dated to around the second millennium BCE, although it was passed down orally for a long period before being committed to writing.

Why is there no completely conclusive answer?

The difficulty lies in how religion itself is defined. If belief in supernatural forces, funeral rites or symbolic behaviour are included, the story begins long before writing. Archaeological evidence of deliberate burials dates back tens of thousands of years, but researchers cannot reliably reconstruct what these populations believed.

• Prehistoric spiritual practices may be far older than any religion known by name.
• Mesopotamian and Egyptian religions produced extremely ancient records, but their original forms died out.
• Hinduism retained ancient traditions while continuing to change across the centuries.
• Zoroastrianism and Judaism also have very ancient origins, and their timelines remain the subject of academic debate.

Other well-documented ancient religions ceased to be practised in their historical form. Sumerian texts from the third millennium BCE, for instance, record extensive pantheons of Mesopotamian gods. A religion can therefore be older in the archaeological record without being the oldest religious tradition that still exists.

Could Zoroastrianism challenge Hinduism for the title?

Zoroastrianism, linked to the prophet Zarathustra, or Zoroaster, is another strong contender among the oldest living religions. It began in the ancient Iranian world, but there is a significant complication: no one knows precisely when Zarathustra lived. Dating his lifetime remains one of the major questions in scholarship on this tradition.

The Encyclopaedia Iranica states that an estimate of around 1000 BCE, allowing for a margin of several centuries, is considered plausible, although scholars have also argued for much earlier dates. This uncertainty prevents a simple chronological comparison with the earliest Vedic traditions that later helped shape Hinduism.

Where does Judaism fit into this history?

Judaism also has deep roots in antiquity, although historians distinguish between ancient Israelite religion and the Judaism that developed later. The earliest known written evidence referring to Israel as a people is the Merneptah Stele, produced in Egypt around 1208 BCE.

Israelite communities were already established in the Levant before 1000 BCE, sharing traditions, rituals and origin narratives. Across the centuries, these practices underwent changes that contributed to the formation of Judaism. Assigning the religion a single date of birth would therefore greatly oversimplify a complex historical evolution.

So which answer makes the most sense?

If the question is about the oldest organised religion still widely practised, Hinduism is the most common and defensible answer. That does not mean it was humankind’s first form of religion. Religious cults and behaviours existed much earlier, while traditions such as Zoroastrianism and Judaism have also endured for millennia.

The most compelling aspect is precisely this: we will probably never know the name, gods or stories of the first human religion. What we can trace is the remarkable survival of traditions that have persisted through empires, migrations and cultural transformations. Examining their beginnings also means considering one of humanity’s oldest questions: who are we, and why are we here?
