It is true that humans, especially in those days, were very limited in knowledge regarding many things we, due to time, travel and science have a clearer understanding of today.
So what makes it ~exceptionally interesting~ then is: how would the Bible writers had knowledge of certain things unknown to humans ?
Here's a few examples:
Some 3,500 years ago, the Bible stated that the earth is hanging “upon nothing.” (Job 26:7) In the eighth century B.C.E., Isaiah clearly referred to “the circle [or, sphere] of the earth.” (Isaiah 40:22) A spherical earth held in empty space without any visible or physical means of support—does not that description sound remarkably modern?
Written about 1500 B.C.E., the Mosaic Law (found in the first five books of the Bible) contained sound laws regarding quarantining of the sick, treatment of dead bodies, and disposal of waste.—Leviticus 13:1-5; Numbers 19:1-13; Deuteronomy 23:13, 14.
This was years before science discovered something called - germs.
Partly as a result of turning powerful telescopes toward the heavens, scientists have concluded that the universe had a sudden “birth.” Not all scientists like the implications of this explanation. One professor noted: “A universe that began seems to demand a first cause; for who could imagine such an effect without a sufficient cause?” Yet, long before telescopes, the very first verse of the Bible plainly stated: “In the beginning God created the heavens and the earth.”—Genesis 1:1.
About 732 B.C.E., the prophet Isaiah penned an ominous prophecy—Babylon would fall. Isaiah provided specifics: A leader named “Cyrus” would be the conqueror, the protective waters of the Euphrates would “dry up,” and the city’s gates would “not be shut.” (Isaiah 44:27–45:3) Some 200 years later, on October 5, 539 B.C.E., the prophecy was fulfilled in all its details. Greek historian Herodotus (fifth century B.C.E.) confirmed the manner of Babylon’s fall.
Isaiah made a further startling prediction regarding Babylon: “She will never be inhabited.” (Isaiah 13:19, 20) To predict permanent desolation for a sprawling city occupying a strategic location was bold indeed. You would normally expect that such a city would be rebuilt if ruined. Although Babylon lingered on for a while after its conquest, Isaiah’s words eventually came true. Today the site of ancient Babylon “is flat, hot, deserted and dusty,” reports Smithsonian magazine.
Also, Archaeological findings supports what was penned down in the Bible:
Bible critics questioned the existence of Pontius Pilate, the Roman governor of Judea who handed Jesus over to be impaled. (Matthew 27:1-26) Evidence that Pilate was once ruler of Judea is etched on a stone discovered at the Mediterranean seaport city of Caesarea in 1961.
Before 1993, there was no proof outside the Bible to support the historicity of David, the brave young shepherd who later became king of Israel. That year, however, archaeologists uncovered in northern Israel a basalt stone, dated to the ninth century B.C.E., that experts say bears the words “House of David” and “king of Israel.”
Until recently, many scholars doubted the accuracy of the Bible’s account of the nation of Edom battling with Israel in the time of David. (2 Samuel 8:13, 14) Edom, they argued, was a simple pastoral society at the time and did not become sufficiently organized or have the might to threaten Israel until much later. However, recent excavations indicate that “Edom was a complex society centuries earlier [than previously thought], as reflected in the Bible,” states an article in the journal Biblical Archaeology Review.
"All Scripture is inspired of God.....men spoke from God as they were moved by holy spirit" ??? Food for thought.
