OK, you are living, say, in the time right after Babel, where all languages were divided, as well as the spiritual seperated from the physical. The continent you are on is moving half way across the world, though it might be noticeable, other things have happened as well. Like life spans suddenly started to decrease, maybe some thing different in the stars, and plants now take a coon's age to grow, causing, perhaps a lot of hunger, and readjustment. (Wait a minute, I think we saw some of that in the Old Kingdom of Egypt, no?).
Now, if I had the time to write aunt Lou, and somehow float the message in a bottle across the planet to her continent, I would reralize we can't communicate any more! So, we might resort to picture words. Hey, that sounds again like ancient Egypt?!!!
Now, being only a century after the flood of Noah, and the ice age going on as well, etc, why, I think we should not expect a well documented, written record.
