Most scholars think the Book of Genesis was written and compiled long after the events it describes, over several centuries, rather than in a single moment by one author.

Quick Scoop: The Dating of Genesis

1. Short, direct answer

  • In traditional Jewish and Christian belief , Genesis was written by Moses roughly between about 1440–1400 BCE (15th–14th century BCE).
  • In modern critical scholarship , Genesis is seen as a composite work whose sources were written between about the 10th–5th centuries BCE, reaching something close to its final form after the Babylonian Exile (6th–5th century BCE).

So there is no single universally agreed date; it depends on whether one follows traditional or critical views of authorship.

Different viewpoints in a nutshell

Traditional / conservative view

Many religious scholars and conservative commentators hold that:

  • Author : Moses wrote Genesis as part of the Pentateuch (Genesis–Deuteronomy).
  • Date : During Israel’s wilderness period, between the Exodus and Moses’ death, around 15th–13th century BCE (often narrowed to about 1446–1406 BCE in one popular chronology).
  • Reasoning :
    • Later biblical books refer to “the Law of Moses” and attribute Torah material to him.
* The narrative flow from Genesis into Exodus fits an origin in the time of Moses in this view.

In this framework, the answer to “when was the Book of Genesis written?” is: during Moses’ lifetime, around the mid‑2nd millennium BCE.

Academic / critical view

Most contemporary biblical scholars treat Genesis as the product of multiple sources and redactors:

  • Multiple sources : Commonly labeled J, E, D, and P (the “documentary hypothesis”).
  • Approximate dates often suggested :
    • J source: 10th–9th century BCE in the kingdom of Judah.
* E source: 9th–8th century BCE in the northern kingdom of Israel.

* D source (mainly Deuteronomy but relevant to Torah shaping): 7th century BCE, associated with Josiah’s reforms.

* P source: exilic or post‑exilic, around the 6th–5th century BCE, often thought to be the last major layer.
  • Final composition :
    • Many scholars place the final shaping of Genesis and the Pentateuch sometime after the Babylonian Exile, often in the 5th century BCE.
* Some specialists still argue for somewhat earlier or later dates (for example, pre‑Persian 6th century BCE or even as late as the Hellenistic period in minority views).

In this framework, the answer is: its parts were written between roughly the 10th and 5th centuries BCE, with the book coming into near‑final form in the post‑exilic period.

Forum‑style “what people are saying” snapshot

You’ll see lively discussion of this question any time it comes up in online forums and Q&A sites:

“Is there somewhat of a consensus between scholars regarding the date also taking into account the oral tradition?”

Typical positions in these discussions include:

  • “Moses wrote it around 1400 BCE” – often voiced by participants from conservative or confessional backgrounds, appealing to traditional attributions and internal biblical claims.
  • “It’s a patchwork finished after the Exile” – often voiced by people drawing on mainstream academic work, emphasizing the post‑exilic compilation perspective.
  • “It’s complicated and layered” – some users stress that oral traditions may be older than the written text, so stories could be earlier even if the written book is later.

A simple example to picture it

Think of Genesis like a long family saga:

  • Some stories could have circulated orally for centuries.
  • At different periods, scribes wrote down or reshaped clusters of those stories.
  • Finally, later editors stitched them together into the single continuous book we now call Genesis, sometime in the first half of the 1st millennium BCE in the academic view.

SEO‑style key points for “when was the Book of Genesis written”

  • The exact date of writing is not known and is debated.
  • Traditional answer: Moses, c. 15th–13th century BCE.
  • Scholarly answer: layers from about 10th–5th century BCE , with final form likely post‑Exile (6th–5th century BCE).
  • Online forum discussion around “when was the Book of Genesis written” often centers on this divide between traditional and critical views and whether one prioritizes faith tradition, linguistic analysis, or historical‑critical methods.

TL;DR: If you’re asking “when was the Book of Genesis written,” the traditional religious answer is “by Moses around 1400 BCE,” while most modern scholars say “it took shape gradually and was finalized centuries later, after the Babylonian Exile.”
