It's entirely possible, because there are too many plants on this earth, and they are always changing, moving, and this is a creature.
-
I don't think so. Because the Earth is just an ordinary planet, its interior is an ecosystem. And the Earth is not a living organism.
-
No. Because the Earth does not have any characteristics of life, and the Earth is only a celestial body, it will not be a "living life".
-
There are only a few reasons why life exists on Earth:
One is that there is a stable energy **, the existence of life needs external energy, only continuous energy supply can develop the initial life, the earth in ancient times had stable geothermal energy and radiation energy from the sun;
The second is a safe external environment, the orbit of the earth is relatively safe, and most of the dangers such as meteorites in the universe are resolved before they reach the surface of the earth;
The third is the appropriate temperature range, the surface temperature of the earth is moderate, so there can be a large amount of liquid water, and the environment composed of liquid water is the source of life, and the first life comes from the ocean;
Fourth, the earth's atmosphere is moderate, which can not only provide protection for the earth's surface, but also allow sunlight to reach the surface.

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 conditions:
Temperature- The earth is at a moderate distance from the sun, making the average temperature on the earth's surface moderate.
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 main reasons for the existence of life on Earth are as follows: the stability of the sun, which provides light and heat; Safe interplanetary space – orbits are coplanar and codirectional, and large and small planets go their own way. Temperature- The earth is at a moderate distance from the sun, making the average temperature on the earth's surface moderate. Atmosphere - the Earth's volume and mass are moderate, causing a large amount of gas to accumulate and form an atmosphere; Water – crystalline water vaporization, pristine ocean.
1. What are the conditions for the existence of life on Earth.
Reason Condition.
External Large and small planets go their own ways and do not interfere with each other A safe cosmic environment has not changed significantly since the beginning of life on the earth Stable illumination itself The distance between the sun and the earth is moderate There is a suitable temperature, and water mostly exists in a liquid state, with a moderate rotation and revolution period.
The Earth's volume and mass are moderate There is an atmosphere suitable for biological respiration.2 The Earth's distribution of land and sea.
The total area of the earth is about 100 million square kilometers, of which about 100 million square kilometers) is land, and the rest of the 100 million square kilometers) is water. The land mass is mainly in the northern hemisphere, with five continents: Eurasia, Africa, the Americas, Australia and Antarctica, as well as many islands.
The ocean includes the Pacific, Atlantic, Indian, Arctic and Southern oceans and their affiliated seas. The coastline is 10,000 kilometers long.

Why does life exist on Earth?
-
There is an atmosphere and an ozone layer, the atmosphere gives the earth air, and the ozone layer prevents ultraviolet rays from destroying life.
-
This question probably hasn't been able to answer you yet, if so, what is the origin of life on Earth? There may still be people who can answer, but why there is one is unknown. It is a mystery whether there will be life forms if there is an environment in which organisms live.
-
Because there are conditions on earth that are suitable for the survival of life.
First, the cosmic environmental conditions: the solar light conditions are stable; The large and small planets in the solar system go their own way and do not interfere with each other.
The second is its own conditions: suitable temperature; an atmosphere suitable for biological respiration; Liquid water.
-
In fact, scientists still don't quite understand why there is life on Earth.
-
Why Earth is the only planet where life exists.
If the universe is a living being, human beings should not be fooled by cells, which should be planets and stars in the universe, and human beings are at most a small part of the cytoplasm of some cells (the earth).
It's hard to say, if it has lived with other dogs with rabies before, it is still a little likely to be sick! But it doesn't look like it looks like you're in the situation. If you do, the wound will become inflamed and not heal, do you have it? >>>More
Won't forget because it's a memory. The first woman in love is the same feeling as first love for most men. Boys have a first love complex, in the era of Dou Chu, they are in their prime, they love each other, that feeling, as if time and space are still there, and the romance of pink flowers is in the depths of memory, there is no reason, no result, no rules, but unforgettable.
Feelings are not lost in a moment, but disappear little by little in the wrong way of doing business.
1. No matter where we live on the planet, we always end up running out of environmental resources. >>>More
