First of all, there is no evidence available like you say there is. Some of the place names and some people names mentioned in the Bible are real, but that doesn't prove the more ridiculous claims. (example: the Harry Potter stories take place in England; archaeologists can prove England exists; therefore the Harry Potter stories are true. See -- it doesn't follow)
That said. There is zero evidence that the Bible is god-inspired or that it is inerrant. Quite the opposite is true. The collection of books known modernly as the Bible is full of errors and contradictions, not to mention several deliberate forgeries.
Most Christians do not even read or follow the book they claim to be their God's word. They just pick and choose what THEY want to observe, and ignore what is not convenient. Which is why they have no idea what their "sacred book" contains, or where it came from.
But, to begin with, the first five books of the Bible (the Torah) began to be written down during the Babylonian captivity (circa 500 BCE) when the Jewish religious leasers realized they had to start writing down all the oral traditions lest they be completely forgotten. In so doing, much Babylonian mythology was "borrowed" by those first writers (the creation account; the flood account -- see the Enuma Elish and the story of Gilgamesh respectively).
The rest of the books of the OT were written and added one by one after that -- including a bunch that were first included then rejected by the Council of Nicea (circa 400 CE); others were then rejected as late as the early 1600s by the translators of the King James Version.
Needless to say there are thousands of translation problems with each "telling" and each editing. This is why so many versions of the Bible exist, and why many editions differ so widely from each other.
It is not true that the Bible "has been proven 100% true over and over again", nor is it true that it has been proven "scientifically accurate". On the contrary, the books of the Bible contain countless scientific and historical inaccuracies, and is even full of huge internal contradictions.
For starters:
-- the Earth is not flat, nor is it just 6,000 years old.
-- bats are not birds.
-- Noah's Flood could not have taken place around the year 2500 BCE because there were already other civilizations in place at that time (see Egypt and China), and these were not destroyed by a flood.
-- there is no independent historical confirmation that anyone named Abraham, or Moses, or Saul, or Daniel, or even Jesus ever actually lived.
-- there is no evidence that a Hebrew tribe actually lived in Egypt as slaves for several centuries.
-- Many historians believe there wasn't even a town called Nazareth until the 4th century CE.
Plus also, if the Bible was the inerrant "word of God" then it wouldn't:
-- contain 1000s of theological problems. (ei. verses that contradict each other; the one god vs. the trinity problem; the law of the Old Testament being observed vs. no laws of the Old Testament being observed; not to mention the inumerable crimes committed by "chosen people of God" against others, including such things as rape, ethnic cleansing, murder, incest, slavery, adultery, the slaughter of entire villages, etc.)
