This question has not yet been clearly answered, and all existing opinions are just at the stage of speculation, and all have their parts that cannot be explained, so such a ** has no practical meaning.
However, I can tell you that the most popular theory now is the theory of the universe, which mainly says that the universe originated from a singularity, and time appeared after a few time periods, and the current state of the universe was formed after several time periods.
The origin of life is even more confusing, and the existing popular theory is to assume that in the state of lightning, nitrogen in the air reacts with oxygen to form nitrogen oxides, and after further oxidation in an aerobic environment, the most basic chemicals of amino acids are formed, and after a long period of complex chemical changes, amino acids are formed, then proteins, then cells, and finally various complex organisms are formed.
But I firmly believe that the origin of life and the origin of the universe are inextricably linked, and if one is completely solved, then the other will be solved, and I believe that if one day scientists figure out how the universe was formed, then they will be able to explain the origin of life.
I feel that the origin of life must be hidden in the formation of the universe, but we have not yet found the golden key to open this door. In other words, the origin of life may be much earlier than we imagine and think, and it may be that the universe began to form, and time has already existed at the moment of formation. Is it really the Creator (God) who makes all things?

So far, mankind has not found a planet in the universe with life other than the earth, but mankind firmly believes that there must be extraterrestrial life in the universe.

The universe in the chaotic celestial body was born, and the universe interacted with each other in a new or unreborn state, and gradually formed galaxies while forming planets, among which galaxies gradually formed n galaxies in the formation process, including a solar system in one of the Milky Way, and eight planets in the solar system, one of which is the earth where we humans now live.
The Earth was lifeless a long time ago, when it was far from the Sun and in the Ice Age. When the earth is getting closer and closer to the sun, it is in the most suitable position for the germination of life in the solar system, and the constituent material of the earth is in line with the elements of the germination of life, after receiving the addition of external matter from the universe, the primordial ocean began to appear on the earth, and the primordial ocean began to give birth to primitive life in the hotbed of the earth for a long time, initially the growth of plants, and after the evolution of plants to a certain extent, simple primitive life appeared, and primitive life began the evolution of life. Among them is the gradual evolution of prehistoric humans.
Prehistoric humans were much larger than modern humans, with a lot of differences in appearance, and their IQ was not high, so they could only be regarded as animals. At that time, the earth had a primitive atmosphere, and the long evolution created the largest life form on the earth--- dinosaurs. Dinosaurs also have their own intelligence, they dominate the earth, and they give birth to their own offspring.
Later, due to some external factors on Earth, including the gradual reduction of oxygen in the air, it was impossible to maintain the continuation of large terrestrial organisms, which led to the extinction of the dinosaurs. This moment is the moment of the rise and prosperity of prehistoric humans, without the wanton abuse of large natural predators, prehistoric humans began to use their minds and wisdom, and gradually combined with nature, understood nature, and used nature, prehistoric humans gradually evolved to the state of primitive man. The key to the evolution of hominids to humans was to learn to use fire and salt.
Nowadays, human beings have evolved relatively maturely, and used human wisdom to transform the earth and study space.

In the silent universe, a dilapidated space warship is moving silently. This is the largest human spaceship built on Jupiter two hundred years ago.
They are looking for the ancestral planet of humanity, which is mostly the origin of Earth's civilization. Two hundred years ago, the earthlings deduced ten trillion times with the most advanced technology that human beings had a near-ancestral planet, but they didn't know where.
In this space battleship, all the members are in a deep sleep at this moment. It was as if they were asleep, unchanged from when they set out two hundred years ago.
Every 20 to 60 light-years, the spaceship automatically identifies terrestrial planets and then autonomously collects nuclear-powered raw materials from terrestrial planets with highly intelligent instruments.
And two hundred years ago, a life technology was added to this space battleship. That is, as long as there is a surviving life in the battleship, the pulse of their heartbeat can drive the battleship.
Twenty years ago, everyone on the ship woke up for a brief two hours. Because they found the first signs of life on an uninhabited planet, and also found a budding flower on the other side.
At the same time, the warship from the planet Ayu has actually arrived on Earth. Endless human wails that they don't think it's real.
The alliance leader of the Alliance of a Community with a Shared Future for Mankind began to call the shots, and the Bronze Space Battleship, the Cangtian Space Battleship, and the God Space Battleship built by the Earth on Jupiter and Mercury ......And so on more than 10,000 ships launched at the same time.
And the billion-dollar hydrogen bomb placed on Mars also detonated five minutes later. This is the darkness that has never been seen in the solar system, an attack from a seventh-level cosmic civilization.
However, the moment the battleship of human pride was launched, they melted one after another.
Backward human beings, humble and ridiculous, you bunches of bugs! ”
A loud voice resounded in the vacuum of the solar system. What kind of method did they use to make the sound conduct in a vacuum?
At this moment, the top scientists in mankind showed helpless self-deprecation. The civilization level of Ayu Planet is too high, and the ability of sound vacuum transmission that they inadvertently show is the cosmic gap that human beings are destined to be unable to surpass.

The origin of the universe has always been an esoteric and fascinating subject. According to the big ** theory, the universe was formed about 10,020 billion years ago, and the age of various celestial bodies is less than 20 billion years, which is in good agreement with the big ** theory. In this theory, the universe started as a very hot and dense point and then went through a process of constant expansion.
As for the meaning of life, it is a broad and complex subject, and different individuals and groups may have different views. The meaning of life can involve personal, social, cultural, philosophical, and other levels, depending on how one understands the nature and purpose of life.
Some people believe that the meaning of life lies in the happiness and fulfillment of the individual, as well as a positive contribution to the lives of oneself and others. For some people, the meaning may come from beliefs, values, relationships, career achievements, artistic creation, etc. And for some religious and philosophical systems, the meaning of life may be based on belief and understanding of the afterlife, reincarnation, soul, etc.
It is important to note that the meaning of life is a subjective and personal concept, and everyone has the right to find and define it according to their beliefs, values, and life experiences. Therefore, the meaning of life is a question that cannot be answered alone, and it needs to be discovered and constructed by each person in their own lives.
In general, the origin of the universe and the meaning of life are two profound and complex themes that involve science, philosophy, religion, and other fields. The understanding and exploration of these two themes not only enriches our cognition and understanding of the world, but also helps us better face the challenges and problems in life and find our own meaning in life.

The origin of the universe is a great mystery, and there are currently many theories about it, such as the Great ** Theory, the Theory of the Expansion of the Universe, etc. As for the meaning of life, this is a very profound question. Everyone's meaning of life is different, some people believe that the meaning of life is the pursuit of happiness and caring for each other, while others believe that the meaning of life is to make the world a better place and contribute to the progress of mankind.
In any case, grasping every day, cherishing the present, and actively living in the empty sky is the best response to life.
