Is there life in the world, is there life on the earth?

Personally, I feel that we were created by "God". The so-called "gods" are extraterrestrial life. They are watching us all the time.

Any mystery is their "masterpiece" or "supernatural". There are also countries and some big countries that are definitely hiding some things that cannot be known. We, "anyone", are just living in objective laws, just to live.

Ordinary us, as a subjective body, just want to live a better and more fulfilling life, there is no need to study the "universe" and "before", we only have the present, we must look forward, look at the people around us, so that everyone can get more exciting, don't be in vain.

We can't know the beginning of each meaning.

Brother, this is a question that thousands of generations of human beings have been thinking about since their birth, and many people have not been able to find the answers in their lifetimes, even today human beings are still exploring the answers to these questions, and I believe that LZ has also thought about these questions more than once.

The world is very complex and very simple, there is no absolute right or wrong answer to your question, what you think and think is actually the best answer.

Life is objective, but it also lives in the subjective life of a person.

Thinking about life is subjective, the existence of nature, the existence of life, and its occurrence and development are objective and not subject to human will.

We people who live just to live feel so small compared to the great men of the world!

The so-called life is nothing more than a definition given by man, and there is no need to dwell on why it lives.

As for the following questions, human beings probably exist to find out the answers.

The conditions for the existence of life on Earth:

External conditions: a relatively stable and safe cosmic environment.

1.Stability of the sun – provides light and heat.

2.Safe interplanetary space – orbits are coplanar and codirectional, and large and small planets go their own way.

Self Condition: Temperature – The Earth is at a moderate distance from the Sun, making the average temperature on the Earth's surface moderate. The letter car is empty.

Necessary for life: Atmosphere - The volume and mass of the earth are moderate, allowing a large amount of gas to accumulate and form an atmosphere.

3.Alteration of the composition of the atmosphere by the action of organisms: water-crystalline water vaporization of the primordial ocean.

The period of earth formation refers to the geological time from the solidification of molten material on the surface to the formation of sedimentary rocks, which is manifested as:

1.The molten material solidifies and shrinks, forming rift valleys and mountains on the surface. Cosmic celestial bodies collide, forming large potholes on the surface.

2.As the temperature decreases, the water flow generated during the solidification of the molten material is delayed into the rift valleys and large potholes, and the gas produced remains on the earth's surface to form an atmosphere.

3.The Earth's core captures the unevenness of the cosmic matter, and the uneven temperature of the earth's surface produces atmospheric flow.

4.During this geological period, gullies, valleys, mountains, and large potholes were formed on the surface of the earth, and with water and atmosphere, weathering, denudation, and transport occurred, and sedimentary rocks began to form.

5.Primitive life proteins appeared, and prokaryotes (bacteria, cyanobacteria) evolved
