It's easy if you anticipate these things. Who put the dead sea scrolls in that cave in the middle of nowhere? Not someone who went in and forgot their scroll one day. Someone who had the foresight that this would be a safe space in the face of who knows what future threat. And it payed off.

I doubt it was that intentional. I would wager that "someone forgot about it" is the more likely explanation.
