The birth of the Earth (about 4.6 billion years ago).
The predecessor of the earth was actually originally a sunspot in the arms of the sun, just like the sunspots in the arms of the sun now, and the predecessors of the nine planets and their moons were all sunspots!
Sunspots are formed by the differentiation of the sun's surface material force. Repulsors radiate into space in the form of photoelectrons, and gravitons accumulate in the form of sunspots to form a vapor-liquid mixture of sunspots or sunspot groups.
When the sunspot stream accumulates to a large size, an extremely powerful radio burst that is suppressed under the cover of the sunspot stream shoots the sunspot stream into space in one fell swoop! Thus forming a new planet or with several moons. The nine planets and their moons were all born and formed in this way, and the earth is no exception.
At the time of the birth of the earth, there was also a sub-black stream, which was ejected by the sun's extremely powerful radio explosion and the earth at the same time, which is the moon! At that time, there were still some small sunspot balls, which had already fallen to other stars due to their early depletion of internal energy.
When the earth was born, it was a steam-liquid mixed vortex with a body temperature of about 1,000 degrees, and after being thrown into space by the sun, it gradually cooled down to form a solid shell ......

45 to 4.6 billion years ago.
The specific development process is as follows: about 4.6 billion years ago, due to the collision of sparse particles around the sun, and gradually concentrated on the equatorial plane of the sun, various planets orbiting the sun were formed, and one of the planets was the earth.
At the beginning of the formation of the earth, the temperature was low, and all kinds of substances mixed together and lived together peacefully. Later, due to the action of radium, uranium and other radioactive materials in the earth's interior, the mountains erupted and intensified, and mountains, hills, and plains were gradually formed. Due to the irradiation of the earth, the temperature of the earth slowly rises, and the chemical action of the earth's internal materials releases a large amount of carbon dioxide, nitrogen, water vapor, etc.
These gases rise to the Earth's exterior to form the atmosphere. Rainfall occurs when water vapour meets cold air currents at high altitudes. The earth is hit by a lot of rain, and in the low-lying places it gathers into oceans, lakes, and rivers, so that plants, animals, and humans are also there.
It took billions of years of evolution for the Earth to become what it is today.

When was the Earth born?
-
1. The earth was born 100 million years ago.
2. The material of the solar system originated 100 million years ago, and about 100 million years ago (about 1% error), the earth and other planets in the solar system began to form in the form of a disk formed by the gas and dust left over from the formation of the solar nebula. Through the process of accretion, the Earth has been roughly fully formed over a period of 1 to 20 million years. From its initial molten state, the Earth's outer layers first cooled and solidified into a solid crust, and water began to accumulate in the atmosphere.
The moon formed relatively late, about 100 million years ago, when a Mars-sized object with a mass of about one-tenth of the Earth's mass (commonly known as Theia) collided fatally with Earth. This early town sent part of the mass of the celestial body to the Earth Brigade Sphere, and part of it splashed into space, and enough material entered orbit to form the Moon.

The Earth was born 100 million years ago.
The material of the solar system originated 100 million 600,000 years ago. About 100 million years ago (about 1% error), the Earth and other planets in the solar system began to form in the form of a disk of gas and dust left over from the formation of the solar nebula. Through the process of accretion, the earth has been roughly completely formed over a period of 1 to 20 million years, and the outer layers of the earth have gradually cooled and solidified into a solid crust.
Surface water also began to form in the atmosphere and gradually accumulated in the process of clearing orbit of icy asteroids, comets, and other celestial bodies.
The Earth is generally thought to have been born 4.6 billion years ago. >>>More
In the past 30 years, scientists have used radioisotope dating to obtain a series of data related to the age of the earth: zircon obtained in the rocks of Western Australia has been measured to be 4.2 billion years old, although this zircon is redeposited in Mesozoic rocks, it is enough to show that the age of the earth is not less than this data; Many of the rocks obtained from the Moon are more than 4.6 billion years old, and since the Moon is a satellite of the Earth and a member of the solar system, the age of the Earth should not be less than the age of the Moon; The ages obtained from a large number of meteorites from the solar system are also between 4,64.7 billion years. According to the basic principle of the identity of the origin of the solar system, the age of the Earth should be more than 4.6 billion years. >>>More
