The Bible(s.) The most perfectly flawed and perfectly compelling documents ever authored since human memory was wiped clean 6 thousand years ago, give or take hundreds of years.
Prior to that folks learned (and remembered) immense bodies of information using what the Jesuits called a "Memory Palace". Noah's Ark, of course, was one ~ and though we have the basic dimensions of the vessel we no longer have the basic descriptions of each of the many tens of thousands of animals on board ~ Moses took care of that part, FUR SHUR, and today we have folks looking for a wooden boat in the mountains when they should, instead, be striving to recover the animal tales.
That the oldest parts of the Bible may well be repositories of encrypted information is not beyond belief. After all, the original "data dump", from oral to written form, had to have had encrypted references so you could keep it all straight. On the other hand, to claim that the information refers to the future is a tad questionable.
