Right, the FACTUAL history we never know... we only know what we perceived to be history, it'll always lack of something, only a part of the puzzle so to speak, or it is some altered history, re-written by someone later.
At least when you look at it through out eyes, there is a true history... but it doesn't exist for us, not in our minds, in our books or anywhere else... but in what might be the "universe's mind" (means: the facts are there, unalterable, but we're not able to perceive them)
It is just as you said

(Just differently expressed

)
However, we can only make... educated guesses as to what refers to the future... sometimes it seems predictable, and we can neither deny nor proove wrong the possibility that the future might already "exist" somehow (at least I can't

) The wide field that is science is still lying bare at many parts... who knows what we know about the mechanics of the universe in some years? Who foresaw what Einstein revealed? There are many unexplainable things to us... unexplainable because our mind cannot perceive them (Einstein just used examples, for example the rubber-membran to show up gravity).
And yes, there are many things we've never seen before, and therefor cannot explain them as well (not only the enigmas we've seen). The universe is huge, and we see only a past reflection of a dust particle, and even just understand it's surface.
Sometimes it just shows how little we are, when we drop the blinders of arrogance, right?
