What is life and what is the meaning of life?

Life: refers to an object that is hereditary, can reproduce, and has a natural process of birth, residence, and destruction. The life currently occurring on the earth is basically carbon-based life.

Life is divided into sentient life and emotionless life. Sentient life refers to life with autonomous consciousness and brain structure. Heartless life refers to life that is hereditary but has no consciousness, such as plants and bacteria.

What is the meaning of life? This question needs to be looked at whether it is the "meaning of an individual's life" or the "meaning of the existence of human civilization as a whole."

The meaning of personal life: Everyone is different. It can be said that the meaning of life exists in every bit of life. It can also be said that "the meaning of life lies in finding the meaning of life."

The meaning of the entire human life: or what is the meaning of the existence of civilization? Existence is meaning. Since we exist and have thoughts, it is to explore more of the universe and understand the universe. Can the universe be fully understood? This again involves the truth of the universe. The meaning of life and the truth of the universe, the end points of these two questions are actually the same. According to quantum mechanics, basic particles have wave-particle duality. Our thinking is also a wave, so the most fundamental thing can be understood as a wave, or as the "wave function" in quantum mechanics. If this theory continues, the universe and our thoughts are one and the same thing. This issue, called "alaya consciousness" in Buddhism, also involves religious theory.

In short, there is no definite answer to this question about the meaning of life. In other words, some people have their own answers to the meaning of their lives, but this answer may not be suitable for others. Everyone should think about and pursue the meaning of their lives.
