Can you scientifically explain whether people have an afterlife?

From a scientific point of view, there is no next life and no last life. Even from the perspective of science and common sense, there can be no so-called past life and afterlife.

Science has proved the basic principles and mechanisms of life. Life is completely a natural phenomenon, there is no mysticism in it, and there is no soul that can be separated from the body. The foundation of past lives is the existence of souls. If science thinks that the soul does not exist, it certainly means that it thinks that past lives do not exist.

The legend about the soul is not credible and cannot be used as evidence of the existence of the soul. For example, it is said that ghosts wear clothes before they die. Are clothes haunted, too If there is a soul after death, there are far more dead people than alive people. There should be ghosts everywhere now. Why do few people see it?

Consciousness is the result of physiological activities of the brain and the product of physical and chemical reactions. Without the brain, it cannot exist independently. People lose consciousness after death, and the so-called soul certainly disappears.

Experiments on souls have not proved the existence of souls. An American doctor did an experiment, claiming that the soul not only exists but also weighs 2 1 g. This experiment is right, but the conclusion is wrong, because such data is meaningless and may be the result of error or physiological changes.

Another experiment said that scientists experimented with terminally ill patients and converted their brain waves into words with computers, only to find that they received information from another world after their death. In fact, brain waves do not contain consciousness information, and there is no technology of "transforming brain waves into words". After death, brain waves will disappear immediately.

Extended data:

In the earth's universe, the total number of life is a fixed number, not a variable, that is to say, the total number of life is unchanged, only the phenomenon of life cycle changes, just like the total amount of water on the earth. The total amount of water is a fixed number. If a place is dry, it is not that there is less water on the earth. If a place is flooded, it is not that the water on the earth has increased.

No new life was born. These so-called "new life" are only transformed from other spaces to the earth. The number of people on the earth has increased, so the number of life in the animal kingdom may decrease, the number of life in the animal kingdom may increase, the number of human beings may decrease, the life in hell may decrease, and the life in the animal kingdom may increase.
