When a person dies, his body returns to nature, originally it comes from nature, and his body is made up of water and various elements in nature. although the structure of elements has changed, it will always exist on the earth according to the’ eternal law of matter’. Since I began to accept knowledge, I have a strong curiosity. I like science very much. For literature, I always think it is a way of expression in life. It is a tool for human communication, emotional communication and telling good grief.. I have been looking for an unknown focus in my study of knowledge. I took part in the work when I graduated from primary school and became an apprentice when I was 13 years old. At that time, my heart was very sad, but my thirst for knowledge has not diminished. I like books such as astronomy, geography, medicine, physics and history very much.. Because I feel it is wonderful to live in this world, as I grow older, I see and hear more and more. I have a strange idea about’ life’, and I want to know what will happen in the future. I have also thought about the moment when the earth exploded hundreds of millions of years later, and then all the life that came to the earth will appear at that moment, and we will also reproduce the space of the earth, because it may have predicted Einstein’s theory of relativity.. Since the power of the explosion far exceeded the speed of light, it took hundreds of millions of years to reverse the time, but the moment of occurrence may be too short and too short. I often think that the universe has designed our human life too short, it can only have that short one hundred years. But think carefully, it seems that man will never die again. In fact, man is made up of two parts, soul and body, soul is a person’s thought, which embodies the goodness and evil of man. The body only represents the beauty and ugliness of human appearance, but the goodness of soul does not necessarily combine with the beauty of body, and the evil of soul does not necessarily combine with the ugliness of appearance. This is an interesting problem because the world is a contradictory unity of opposites.. When a person dies, his body returns to nature, originally it comes from nature. his body is made up of water and various elements in nature. although the structure of elements has changed, it will always exist on the earth according to the’ eternal law of matter’. I remember someone once said such a thing,’ either we live forever or we live forever. I want to say this sentence people must understand what, yeah! When a person stops breathing, his soul and spirit return to space. He has been floating in space, waiting for the living to accept him and his thoughts and spirit, thus returning to the world.. Human beings are always searching for beauty. How many people still live in our hearts since ancient times. He ( she ) has given the posterity spirit and strength, and many evil soul thoughts are in the world, but he is always telling posterity not to reappear.. The soul is the spirit and thought, and it is also the real life of human beings.
