Why is the appearance of ancient great men always accompanied by the occurrence of certain celestial phenomena?

The emergence of great men in ancient times is always accompanied by the occurrence of certain celestial phenomena. I think this is a fabrication made by historians to increase the rationality of the emperors’ status. The reasons include: after the emperor became an emperor, everything was in ruins, and people were not yet united. At this time, a belief was needed to guide them; during the feudal period, productivity was low, and many phenomena could not be explained, which made people believe this; historians of the past dynasties, in order to To cater to the emperors' wishes, they fabricated and exaggerated their lives.

There are many great people in the history of our country. Some of them have made great achievements in natural sciences, such as Guo Shoujing; some are talented in the military field, such as Bai Qi; and some are in building a country and governing society. Those who have outstanding performance in this aspect, such as Liu Bang.

Reading history books, we find that the appearance of ancient great men is always accompanied by the occurrence of some kind of celestial phenomenon. Why is this? I think:

The root: the ideological foundation of ancient emperors’ imperial power and divine power

We can find clues from the uprisings of Chen Sheng and Wu Guang, where words were hidden in the belly of fish, and He also used the bonfire and fox calls to create public opinion and enhance his credibility. Only then they failed.

Objective conditions: During the feudal period, productivity was low

In the feudal period, productivity was low, which provided objective conditions for these fabrications. People could not find a reasonable explanation in real life, and there was no science at that time. People were in a state of ignorance, and more people chose to follow the crowd and follow what others said.

Subjective reasons: Historians catered to the emperor when they compiled history books

Historical books are written by historians and are about previous history. During the tenure of the emperor, or during the tenure of the emperor's sons and grandsons, they would inevitably cater to them in order to keep their official positions, such as Sima Qian, so the above-mentioned phenomenon occurred.
