The Bible was written over a very long period of time by around 40 different authors.
- The earliest writings, likely including the first book such as Genesis or Job, were completed around 1400 BC.
- The Old Testament (Hebrew Bible) was composed and compiled over about a millennium, with some parts possibly dating back to as early as 1200 BC.
- The New Testament was written much later, within the first century AD, primarily between about 50 AD and 100 AD.
- The last book of the Bible to be written is generally considered to be the Book of Revelation, authored by the Apostle John around 90-95 AD.
Thus, the Bible as a whole spans a writing period from roughly 1400 BC to 95 AD, making it between about 3,400 and 1,900 years old depending on whether you count from the beginning or completion of the texts.
