In scientific terms, is there an afterlife?

In pure science, there is no afterlife. In the biological sense, man is an organism composed of protein. Once a person dies, protein will be eaten by saprophytic bacteria ... Needless to say. People's afterlife is generally soul theory, which holds that people can be reincarnated through reincarnation because their souls and spirits are immortal. But scientifically speaking, people have no soul. The reason is that if a person really has a soul reincarnation, then the person who has been reborn should have memories of past lives, but this situation hardly exists. It can be seen that "soul reincarnation" is not a common phenomenon. Another reason is that people are made of pure matter and there is no so-called spiritual energy. When people die, thoughts disappear (people's thoughts are actually supported by chemical reactions in the brain). Without hundreds of thousands of chemical reactions in one second, everyone is a thoughtless plant. Therefore, according to pure "science", there is no so-called afterlife. This is the mainstream idea of living less.

As for fate, it is the power of probability in mathematics, or the embodiment of love over time. Only people you know will have the feeling of "fate", because people you know will pay more attention to their friends and family, so it is normal for them to have some coincidences and feelings. On the contrary, we don't feel this way about strangers on the road, but there is a counterexample. For example, we saw a stranger on the road who was a Chinese medicine practitioner. Although I just passed by in a hurry, I met this person again and again. Then this can also be said to be "fate", but in terms of probability, this is only a very unlikely coincidence.
