Well said, RtS. Perhaps for the same reason they kept the Ark of the Covenant when Indiana Jones found it. They just put it in a big box saying "do not open" and shoved it into a giant warehouse. Why? Perhaps that's their inept factor creeping in, or perhaps they want them to be found (she said darkly). Maybe that's part of the conspiracy too. Maybe we're meant to think there are X-Files... oh bollix, my head's all messed up now. There's no way I'll be able to start the revolution now.
