The birth of the universe was a magnificent fireworks show that began with a great explosion. In the Big Bang model, the infant period of the universe is opened in a violent explosion.

The explosion not only released unimaginable energy, but also synthesized hydrogen, helium, and small amounts of lithium, beryllium and other elements in an instant. These elements make up the primordial nebula of the universe.

隨著時間的流逝，這些星雲在重力的作用下開始坍縮。在宇宙大爆炸後約4億年，星雲坍縮形成了第一代恆星。這些恆星內部進行著核聚變反應，合成了鐵及之前的元素。

In the explosion of supernova, the elements after iron were synthesized, and they were thrown into space, mixed with the original nebula, providing a rich material basis for the formation of subsequent planets. The sun, the planet we live on, was born in such nebulae.

The formation of the solar system is an exciting chapter in the long history of the universe. The nebula collapse theory reveals the mystery of this process for us. In the core region of the nebula, due to the high density of matter, gravity causes the nebula material to continuously gather towards the center, and finally forms the sun. The rest of the nebula's periphery collapsed into various celestial bodies such as planets, dwarf planets, and asteroids.

The planets within the solar system can be divided into different categories based on their location and nature. The inner solar system is made up of rocky planets, including the well-known Mercury, Venus, Earth, and Mars. Because of their proximity to the sun and their high temperatures, they are mainly made up of rocky materials that are difficult to evaporate. And in the farther regions from the Sun, beyond the freezing line, gas and ice giants such as Jupiter, Saturn, Uranus, and Neptune are formed. These massive planets are mostly made up of gaseous and icy material, as they are located in areas that are cooler and less prone to evaporation.

The peculiarity of the Earth is that it is the only planet in the solar system that has a lot of liquid water. Water is the source of life, and it is precisely because of water that the earth can give birth to the miracle of life.

生命的誕生是一個神秘而奇妙的過程。根據科學家的研究，地球上的生命可能起源於約45億年前。當時，地球還是一個熾熱的球體，頻繁的火山爆發和電閃雷鳴為生命的誕生提供了條件。在原始的海洋中，無機分子通過化學反應逐漸合成了有機化合物，從而誕生了最初的生命形式。

Over time, life has evolved, forming a complex and diverse range of organisms. However, the course of life on Earth is not all smooth sailing. There have been several large-scale extinction events in history, the most famous of which occurred about 000,0 years ago, when an asteroid impact led to the extinction of the dinosaurs, leaving room for the development of mammals. In these mass extinctions, only the most adapted organisms survive.

In the long river of life, the emergence of human beings is an important milestone.

人類的遠古祖先可以追溯到約580萬年前的人族動物，再到250萬年前的早期人類。隨著時間的流逝，智人在約50萬年前的非洲演化出來，並最終擴散到全球。智人的演化過程中，大腦容量的增加和工具的使用是關鍵因素，最終導致了現代人類的誕生。

The dawn of civilization began in the plains of Mesopotamia around 3500 BC, where the Sumerians established the earliest written and city-states, marking the beginning of human civilization. Subsequently, the flame of civilization was gradually ignited around the world, and human society began to develop at an accelerated pace.

The birth of science was in Europe 400 years ago, Galileo is known as the father of science, he broke the traditional understanding of the universe and started the scientific revolution. With the development of science, human beings have a deeper understanding of the natural world, and the progress of science and technology is also changing with each passing day. Today, humans have been able to explore the depths of the Earth, fly into space, and even begin to study the origin and evolution of the universe.

Mankind's exploration of the origin of the earth and the universe has never stopped. Countless scientists and explorers are working to unravel the mysteries of the universe, whether through observation on the ground or in space, and humanity's desire and curiosity for the unknown are driving us forward. In the future, with the advancement of science and technology, we may have a deeper understanding of the universe, and even discover the existence of extraterrestrial life, opening a new chapter in cosmic exploration.
