What do you think the existence of life means for the planet?

The existence of life is to change the earth and maintain the earth, because if there is only the earth and no life, the earth can only exist by itself, and with the existence of life, the earth will have different possibilities.

I believe that the existence of life can make the earth colorful, because the earth was originally a deserted planet, but because of the existence of life, the earth has become rich.

The emergence of life is the proof of the further development of the earth, the emergence of life is the vitality of the earth, the beginning of full of vitality, the emergence of life, but also the emergence of the earth to carry out self-circulation, so as to develop better.

Life fills the earth with vitality, and life makes the earth's cycle faster. Life is also the reason why the Earth is greener, and it can also make the Earth bluer.

I think the meaning of the existence of life is to make the earth more beautiful, and the existence of some life will actually make the earth more colorful and lively.

It is life that makes the earth more colorful, and if there is no life, the earth is very boring, only those animals, they have no thoughts, they will be very boring.

Because there is life on the earth, the earth becomes vibrant, and the world can become rich. Because of these lives, the earth has its meaning of existence.

Because of the existence of life, the earth will become more meaningful, and he gives these creatures a certain space and environment for existence. In this way, the world will become colorful.

Because there is life on the earth, it is the earth that becomes different from other planets, it is the earth that becomes more vibrant, and people's creativity gives the earth a different place.

If there is no life, then what is the difference between the earth and other planets, it is precisely because of the existence of life that the earth has become unique and a magical planet.

The distance between the sun and the earth is moderate, and the temperature is suitable.

There is liquid water; The Earth's moderate volumetric mass allows the Earth to attract an atmosphere suitable for living beings to breathe.

The sun's illumination conditions are stable.

The nine planets orbit the Sun in a coplanar and isotropic manner, and do not collide with each other. Therefore, the interplanetary space in which the Earth is located is safe and stable.

In short, the reason for the existence of life on Earth is stable light conditions, a safe cosmic environment, a suitable atmosphere and temperature, and liquid water.

The reason for the existence of life on Earth:

1. Planets protected by magnetic fields in the habitable zone.

Theoretically, every star in the universe has a habitable area where life can occur, and the Earth is located in the most suitable habitable area, a little closer will become a hot planet like Venus, and a little farther away will be as cold as Mars.

Moreover, the particle wind emitted by the sun has strong radiation and ultraviolet rays, which are very lethal to life, but the earth's magnetic field and ozone layer protect life from the space environment, and the earth's seasonal changes and sufficient sunlight give the earth a chance to appear higher life.

2. The indispensable moon.

Some scientists once believed that without the moon, there would not even be ocean currents and monsoons on Earth, and that life in the ocean would not have evolved into higher life without the nutrients brought by the tides.

The gravitational pull of the moon ensures that the earth has a climate with four distinct seasons, and the moonlight at night also gives rise to special nocturnal creatures on the earth.

3. Conservation of multiple planets.

The most terrible disaster for life on planets is the impact from meteorites, which also makes some planets in habitable zones unable to have life at all, but the reason why the Earth rarely suffers from meteorite impacts is mainly due to the gravitational field protection of Jupiter.

Jupiter's strong gravitational pull absorbs most of the wandering objects that will hit the Earth, and even those that break into the Earth's orbit have basically hit the Moon, and it is difficult for the Earth to have advanced life without the protection of these objects.

Fourth, a safer location in the Milky Way.

The closer to the core of the galaxy is easier for intelligent civilizations to obtain resources, but carbon-based life forms are not suitable for these core regions, because the gravitational pull of black holes makes planets more vulnerable to devastating meteorite impacts.

At the same time, stronger black hole radiation has a fatal blow to carbon-based lifeforms, the solar system is on the outer spiral arm of the Milky Way, the interstellar space here is relatively empty, and all kinds of cosmic rays have not reached the point where they can affect life, which is the best choice for the initial development of intelligent civilization.

5. Stable atmosphere.

It is hard to imagine that the earth can produce higher life not because of enough oxygen, but because of the nitrogen gas, which accounts for 78% of the atmosphere, and nitrogen is a very stable gas compared to other gases.

Not only will it not pose a hazard to carbon-based life, but it is also the main nitrogen fertilizer necessary for plant growth, and at the same time, because the ozone layer on the earth resists most of the cosmic rays, so that the organisms on the surface can get enough sunlight without being harmed.

The reason for the existence of life on the earth, external conditions: a relatively stable and safe cosmic environment. Stability of the sun – provides light and heat. 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, resulting in an average temperature of 150C on the Earth's surface. Essential conditions for life The atmosphere is moderate in volume and mass, so that a large number of gases accumulate to form the atmosphere by the action of atmospheric organisms.

Water – Crystalline water vaporizes the primordial ocean.

A lifetime only needs food and clothing, but in essence it is only a temporary life. The meaning of life for everyone does not need to be mediocre. World Bureau.

Those who dare to face the waves of life are the real strong, and they should refer to the relative meaning. Life is a fun and meaningful life.

From an evolutionary point of view, the one who dares to face the waves of life is the one who is truly strong and does not live for others. The past life is useful for this life, but for the sake of his own selfish desires, it cannot be ruled out that there are similar animals on his planet, and he has been wronged by his face. This kind of life is interesting and meaningful, and I strive to pursue my life goals every day.

If you are punished and punished, you might as well try to do something meaningful in this life.

The following figure is an example: <>

Everything is for the people who look forward to it, and we must know how to pursue it unremittingly.

All life is a passive advent, so it is instinctive, and there is no meaning. To live, to live this life completely, that's the meaning.
