The Dead Sea Scrolls were found in the decade after WW-II and dated by secular archeologists to a couple hundred years before Christ. There significance is they said the same thing as the Bible on your grandma's coffee table. No changes in over 2000 years!
So this puts to rest the idea that Scriptures must have been corrupted over time "because that's how humans always screw up". Clearly that didn't happen with the Bible.
