Regarding how much people don't know about history, I saw something somewhere (Cracked maybe) that said only like 3% of human history is recorded. That blew my mind when I read it and it still pops into my head at times.
I would suggest that 3% is very optimistic, especially if we are talking written history.
The first narrative historians don't appear until the 5th century BC and are limited to the eastern Mediterranean. Before that we had a few local chroniclers, poets and royal records.
