Because he is human, he wants to live forever. It certainly helps to think like this. People can't evolve without thinking. Just like when humans were apes, they thought about when they could not be bullied by tigers and lions. Every time a tiger and lion come, several companions will be robbed. What do we do? Later generations gradually invented various stone tools and hunted wild animals. In ancient times, people thought about when they could not be afraid of freezing in this cold weather. What should we do if we live in so few caves? Then someone invented how to build a house. In ancient times, people thought they could eat enough without worrying about food. What should we do if wild animals don't have enough wild fruits? Later, someone came up with a way to grow grain and kept six animals in captivity. In ancient times, smallpox, cholera and plague were rampant, and one person died in a large area. Later, there were various vaccines to eliminate these plagues! Once upon a time, I went to the moon for nine days and went down to the deep sea to catch dragons, clairvoyance and clairvoyance. Sitting at home, I know what is happening in the world. fairies live in a cave, where summer is warm and the seasons are like spring ... these are impossible wishes. Can't you see it's all realized now? What makes you say that people can't live forever? Because the ancient emperor died after eating Dan medicine, did he give up the pursuit of immortality? This is the greatest pursuit of mankind! Seriously, in theory, a sense of immortality can also be achieved.

Although any matter will be reincarnated, even the world will rot and end, so the body is basically impossible to be immortal. But the intangible information energy can still be eternal, so in theory, people's self-consciousness, the so-called soul, can be eternal, and people can completely obtain this eternity through technical means. That is, a communication chip that can store memories is implanted in the brain (it is being tested, and a safe finished product should be produced within ten years) to record all the thoughts and memories of a person's life. You can connect to the network at any time and upload your thoughts at any time, and make a memory backup in the cloud server. When an individual dies unexpectedly, after the death of the individual is confirmed, the backup memory can be loaded into a new carrier to activate and restart consciousness. In this way, for you, you are reborn only by transferring consciousness (soul), just like the reborn protagonist with memory in countless novels. Theoretically, this method can be infinitely reborn, that is to say, in a sense, the soul is immortal.
