Well, when it comes to the Bible, I used to be a "King James Only" guy. However, I have concluded that the KJV is just a good translation but that there are many other useful sources.
For example, to understand the history of mankind and the formation of the earth, the non-Canonical books of Enoch and Jasher fill some important blanks.
To understand the context of the events around Jesus' death, the Bible is light on some detail. However, secular historians like Josephus are a popular go-to along with Polycarp, Tertullian, etc.
So, truth be told, I do have confidence that God preserved his Word, as evidenced by the Dead Sea Scrolls discovery at Qumran in 1946. However, I also believe that secret societies have hid much for millennia.
The funny thing about secret societies is that their members die off, and their next of kin often don't know what to with the libraries of the deceased.
So while just about any Bible translation is sufficient to understand the Gospel, to understand the history of the world, it is often not sufficient even though the Bible has never been proven wrong on anything.
For example, Job is the oldest book of the Bible. It gives us some gems, e.g. Pleiades, Mazzaroth (a.k.a. the Zodiac), Orion's belt, Ursa Major and Minor. See "The Witness of the Stars" by Bullinger.
