Keep in mind that many people have straight up lied about their abilities (E.g. kakashi about his sharingan) or concealed their true strength (Kakuzu until he started using the black creatures, Nagato's whole schtick, etc).

So i presume they become scientists/historians because both they and shinobi obviously share our nature - desire to know everything. So appeare of supernatural things like chakra and Ten-Tails can be considered as revolution of people's understanding of universe and creation of manuscripts. Well, how much would regular people really have seen of Kaguya to really make mentions? Plus in the real world, revolution was rarely peaceful, causing massive destruction. It's possible that what references of Kaguya existed were burned en-masse for being heretical.

Plus, a clan was named after her, so it's possible that many people eventually confused the goddess for the clan.
