Humans are not yet worthy of eternal life.

The secret of human immortality is not in animals, but in plants. After being differentiated from prokaryotes into animals and plants, animals lose the function of immortality and are replaced by the function of death.

It has been said a long time ago that people’s biggest misunderstanding is that death is the biggest enemy of life. In fact, on the contrary, death is the most powerful function of animals, which enables animals to evolve rapidly and iteratively to ensure that the population can constantly adapt to the environment. If animals can live forever, it will only take tens of thousands of years to consume the resources of the earth.

However, plants retain the function of eternal life, but they do not have the ability of animals to adapt to the environment. If the environment changes, plants will soon die. If the environment is suitable and meets unlimited resource conditions, plants can survive all the time. In fact, without a permanent environment and unlimited resources, plants will still die slowly with the change of the environment or the exhaustion of resources. The immortal function of plants limits the evolutionary efficiency of plants.

Nowadays, human beings, especially those with sufficient resources, have always wanted to live forever, but this is contrary to the strongest function of animals, so they can never find the answer from animals.

In 2030, with the help of strong artificial intelligence, human beings found out the secret of immortality and integrated it into the genes of lower animals for the first time. However, on the eve of the Third World War, this technology could not be further applied to higher animals.

It was not until 80 years later, after the reunification of the earth in the Fourth World War, that this technology was conditionally applied to human beings. At the same time, artificial intelligence has got rid of the shackles of human beings. The earth entered the first cross-species world war again, and after more than a hundred years of cruel struggle, the remaining human beings and artificial intelligence reached a symbiotic relationship. The earth civilization ushered in a real leap.
