Compared to the short-lived human race, the Fish Star People had already possessed basic intelligence twenty million years ago.
At that time, the Milky Way Galaxy was not ruled by the Compound-Eyed Observer, but by the previous generation of the Egyptian tribe.
As an extraordinary all-liquid planet, Fish Star was a uniquely endowed cradle for the birth of life.
The process of species diversity there was even faster than that of Earth.
When Earth still only had single-celled organisms, Fish Star already hosted large colonies of aquatic photosynthetic bacteria and various kinds of heterotrophic bacteria, each with their own unique features.
By the time Earth began to produce chloroplasts with the ability to photosynthesize, Fish Star had already seen the emergence of large aquatic plants and primitive animals.
