Considering that she and her clan lived among other people, there were a lot of them who could register information about her for future generations.

Also, Gokage didn't know about Ten-Tails either, indicating they lacked of knowledge about it too.

So how is it possible for Ninja World to be not informed about events in the past? Does it mean that history as a science in this world is hardly developed? I think you hit the nail right on its head on that one. Subjects like History and Geography were only taught when it served a shinobi and I don't even think they went that far in time. I mean, Sasuke was top of his class, 16 years of age and still was hazy on who exactly Madara was AND he was not even a celestial, half-mythical being like Kaguya - he had been alive and kicking around 80-90 years ago. Only after the Fourth War and during the events of Boruto is a more conventional curriculum introduced in The Academy.
