All of these things were terrible events and should be remembered. Animals return, plants reestablish themselves and new people settle again in the area. An older person might remember the event for a time, books and articles are there for the youngsters, but except for technical personnel, such as architects, geologists, or the like, the memory fades. And so it is with astronomy. A star will flare silently in the night, a few meteorites streak across the sky, a fog covers the moon.
Most people are asleep.
Exhausted from their daily labors, they sleep with no inkling of stellar events. On rare occasions, there is a continuous display in the heavens that someone took notice of because of its beauty, and others are told. If these were very impressive events, they are recorded for posterity in lands where writing systems were used. In areas where there is no scribal ability, stories were told and these became myth or fable. In Peru, there are several such star events that are recorded as myth, which were also illustrated in art.
