Think of the state of the historical record of world history known to academics 2,000 years ago. The Greeks were uncertain about history predating the Heroic Age circa 1500 b.c., just the names of reptuted gods and their progenies having been passed down by oral tradition ’til writing was begun during the Heroic Age, the Romans’ knowledge really much the same, with the Chinese having had a rough template of ancient emperors and history back to circa 2000 b.c.
The Egyptians clearly didn’t have much of a clue, having told the greek Solon circa 600 b.c. for their Atlantis story that the bronze age and Greek history preceded their time by 9,000 years, the ancient Egyptians clearly masters of historical exaggeration and distortion, with the rest of world’s people groups having similar vague ancestral recollections with no hard timelines established, oral traditions of ancient times long past
So when the Bible was brought to the world after the writing of the New Testament, the veil of ignorance came off the ancient people groups’ understanding about their ancient histories, then seeing that the Table of Nations in Genesis 10 documents their origins, for instance that the global flood of Deucalion in greek lore was Noah’s Flood, the greek “gods” following real men, such as Sidon who was Posidon, Atlas who therefore was a grandson of Canaan, and Javan (greek Iawon), grandson of Noah, who was the namesake of the Ionians.
The ancient Babylonians knew of the legendary global flood, their flood of Utnapishtim, their timeline for that catastrophe almost in line with the real chronology, yet their records were discountinued, while the Hebrew historical records were kept entact and expanded as the events unfolded, all recorded in the Old Testament, the Dead Sea Scrolls confirming that those records were never changed, records even from Adam and Eve seeing http://genesisveracity.com/Articles/Article13.htm, seeing the science of biblical history here http://genesisveracityfoundation.com.
