I imagine there is much that is forgotten. Look at how the archaeologists scramble to preserve every little scrap of the past they find: they know how much of the past is beyond recovery, how much has vanished with the shifting of the sands. I imagine the denizens of those thousands of years ago did not find the items now treasured so precious. It was just stuff to them, and there was a lot of it. It makes you wonder how much of the stuff of these days will one day be treasure, in many thousands of years: how much of what we throw away without a second look will tell about us to they who would look into the past and wonder why? True, we write down much of what occurs, but in my thinking, they in the far future shall wonder (as we do, sometimes) what really happened here.
In your own life, in your personal happenings, there is much there that we dismiss. There is that notion that every little thing that happens to us affects us in some small way, but usually, the marks that are left are very little indicative of the things that made them. We find many of the things that occur boring, or routine, not worth the bother to store in long term portion of our cerebral cortex. We forget, and never wonder why these things ever were, whether the little happenings ever tipped the scales on some emotion or decision without our realizing, why we should ever care about them at all. But what small things keep you safe, keep you sane, keep you going? I bet you don't know; I bet the best we can do is remember that we forgot, a million little things never considered.
