Quote:Didn't a group of Jews write this down 3,500-4,000 years ago?
No. Somewhere around 2,600 years ago they may have started to write some things down...after plagiarizing much from the older and wiser Sumerian culture. As near as we can tell they did not have a written language until sometime around 900 BC and we certainly do not evidence for extensive literacy then.
And, before you make things worse, the oldest OT texts in existence are written in Greek. Not Hebrew. The Septuagint dates from the 3d century BC.
