How long ago was the Bible written?

Answer 1

Different parts of the collection we call The Bible were written at different times. The New Testament was mostly written early during the first century AD (so around 2,000 years ago); some parts of the Pentateuch (the first five books of the Old Testament) probably go back to around 600 BC (around 2,500 years ago).

The books were first assembled into what we now call the Bible around 370 AD (1,600 years ago) by St Jerome working under the supervision of Pope Damasus I.

An additional thought:

Some of the most anciently inspired books of the Bible may have been written before the flood... by the Faithful of God, like Enoch [Abel? Noah?].

In his 120 years preparing the ark, Noah had plenty of time to accumulate and include among his cargo literary documentation... which may well have ended up in the renowned Egyptian library, centuries later... some of which God may have alerted Moses to take with him upon the Israelite's departure.

Moses would have become familiar with the contents of the library in his youth... being reared and educated in Pharaoh's own household as a son. And, no doubt, such writings would have been helpful to Moses [along with God's inspiration] in his penning of Genesis.

As stated above: the books of the Bible were written throughout the centuries as God inspired men to do so. And "how long ago" these writings began, almost with a surety, began with some of the Faithful of God in the first few generations of man's existence.
