When a person dies, all life activities stop. The various substances that make up the body will gradually become other organic substances, and all kinds of energy are constantly changing. These substances that make up primitive life can never be reassembled back into primitive life.

Some absurd phenomena are mostly chemical and physical phenomena (such as optics), while others are caused by human hallucinations.

People's thinking process needs energy, but thinking itself is not energy. Man's "soul" is an external behavior under the guidance of man's internal psychological factors and psychology. The so-called "soul" is not energy, and certainly not matter.

If there are ghosts, there have been hundreds of billions of ghosts around us since the birth of mankind, and countless ghosts of animals such as pigs, chickens, ducks and dogs will "play" around you, so it is not something that a few people can meet, but everyone can meet at any time! Have you met at this moment?

Therefore, the existence of "ghosts" does not exist, it is just a means for some people to scare others, or they scare themselves!
