Biblically, the beginning of the earth was after the forming of God in Genesis. Thousands of centuries later, the scientists put on hypothesis how the earth was made according to their theories.

Genesis 1: 1-2 English Standard Version (ESV)
The Creation of the World
In the beginning, God created the heavens and the earth.The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters.
-Genesis-
How was the earth formed? Who made it? Where is it from? What's its origin?
People in antiquity explained the formation of the earth by mythologies (excluding the Bible) but those ended up into fictional stories. The listeners sought for deep answers. They studied and observed the movements of the skies carefully. They had no high-tech devices to see the stars and moon clearly. Yet, they can understand many things from the skies. They discovered that stars are formed into groups in the nightfall after bonded itself. They moved. Not just the stars, they knew that there are a few strolling objects. Since then, those circling objects are named 'planets', that defines 'wanderer' from the Greek word.
The planet we lived in, the moon, the different planets with their moons belong to the solar system of the sun. The planets that surround the sun are its moving shields named orbits. Earth, our planet, is the third sphere from the outer area of the sun.
Since no one really knew the origin of the earth scientifically, there were new and improved theories came out. They were curious about the beginning, its origin, and the forming of the solar system.
THE FIRST THEORY

Pierre Laplace from France is an astronomer and mathematician born in 1796. He released the nebular hypothesis on his presents. According to the English translation, the hypothesis is an explanation according to the evidence. The word Nebula comes from the Latin word. In English, it stands for 'cloud.' According to his discovery, our atmosphere contains water vapor formed by gas and dust elements. These are called clouds or many nebulae.

Laplace assumed that the sun was a cloud. The cloud rotated to a hot gas until it was formed into a round shape of a massive ball. As the cloud spun around the gas, it became round. While the ball embraced the cloud, the cloud lost its size slowly into a thinner dimension than its early shape and rotated faster. The alteration caused the ball to lump in a midpoint of the equator and crushing the poles. The gas and dust formed of ring started to surround the equator. These objects collided from the equator and some pieces were tied up again to form another planet. This planet encompassed round the remnants of the cloud. The clouds continued to shrink and rotate speedily, unstoppable to produce more rings, collided, and formed a planet. Ultimately, a class of planets going around a central spheroid of thermal vapor- the creation of the sun. This report sounds understandable. Many people were convinced that it was how our planet began and its sister planets.
As more discoveries were determined regarding the sun and the planets, the Laplace theory slowly lost its approval. The primary issue was the evidence that the sun twirls moderately. If Laplace's hypothesis was correct, it would revolve quickly. Perhaps, the sun became slowed down, though no individual can tell how this could happen. So astrophysicists had to rediscover again.
THE HYPOTHESES OF THE LITTLE PLANETS
In 1900 era, two American astronomers Thomas Chamberlin and Forest Moulton promulgated new idea. They called it the planetesimal theory. ('Planetisimal' defines 'little planet.')
A few years later, the British astronomers Sir James Jeans, and Harold Jeffreys introduced different assumption named the tidal theory. There were a few disagreements linking the theories of the British and American, yet the main point was alike.
At first, their theories explained that the sun is not surrounded by planets. Then, centuries ago, it reached nearby to another star. The bodies were used to drag of gravity on another. The proposed tidal waves of burning gas that rolled throughout both sun and star. As they moved each other, currents of gas were stretched out toward space separating two bodies. When the certain two bodies drifted apart, any of the flows of gas compressed to develop planets.

These, too, seemed like valid theories. However, scientists had discarded those. For one reason, the moving stars are not given any planets to supply a powerful motion to pivot around the sun. If that's the case, they would just fall turning back to the sun and burn. Plus, both hypotheses were on the opportunity of a star that passed nearby to the sun.

Astronomer Coryn Bailer-Jones prophesied that the stars will stay closer to the sun which is the greatest threat on earth. The passing stars might disturb the sources of light from the Oort Cloud, the comet that extends light year sourced from the sun.

THE THEORY OF THE DUST CLOUD
The example of catastrophic theory which was thought that planets were created by a sole star by mishap.

Astronomers added new proposals about the origin of the earth in two kinds: natural theory and evolutionary theory. Both hypotheses hint that the planets are created round a star, Then the star was made, or they developed a portion of its natural cycle. Laplace's nebular theory is alike. A new catastrophic theory was then named. It is said that the planets are formed by an accident or catastrophe like the collision of the stars. The planetesimal theory besides believed this principle.
It is essential to identify which theory is true. However, scientists certainly discovered that the stars need planets most. But if the theory of an accident is right (catastrophic theory) about the origin of the world, then the conception of our universe and the cycle on it is rather a strange phenomenon in the annals of the world. Stars are distant and isolated that mishap comprising two stars is extremely wonderful. In actuality, throughout the duration of our solar system- that is 4, 600, 000, 000 ages only 1 within every 10,000,000,000 stars can gain planets through it.
Scientists can identify planets surrounding the other stars. Telescopes cannot be used this time because they're very distant. They discovered that planets interrupt the movements of the stars. Their movements are easy to see. The natural theory and catastrophic are almost the same. Many people were convinced of Laplace's theory (nebular theory) as accurate in the outline.
Astronomers now considered that the forming of the stars and the planets were caused by the rotation of the cloud with dust and gas. In 1940, Carl von Weizsacker developed this additional hypothesis called the dust-cloud theory.
Throughout the world, there are enormous vapors of powdered particles and gas 5,000,000,000 years before. According to a particular assumption, a great number of the dust particles inside such a smoke started to compress and develop a globule. Some particles were dragged near the axis of globule frequently because of the interactive gravitation. When the globule transformed into a round shape (a ball), it was activated to spin. The rotation made it straighten out. The disc axis was spinning more gradually than the outside parts. It started to compress even more. Finally, the energy delivered by this method turned the temperature and its pressure within the globule becoming so powerful. It was the beginning of the thermo-nuclear processes. Then, the world was portioned by the light of the star-the- sun.
The external portions of the dust cloud remained spinning too active to consolidate into a whole mass. They busted up in tinier, rolling pieces of gas and dust, that compressed to develop planets.
Some particles of dust and gas were continued to condense to produce many stars while the building of the solar system was ongoing for a million years.
WHAT WAS THE LOOKS OF THE EARTH
What did the recently made earth look like? Did it look like a sphere of a burning gleaming rock? Was it frozen? Was it water? These mysteries are very significant to geologists that study the universe.
Geologist now coordinates on a global image of the young planet. The earth created as dust pieces grouped collectively in a nebula in place. The particles drew each other through gravitation so those mass particles gathered together and developed a substantial globe. As the power of gravity of the spheroid pulled in more particles, the distinct world grew bigger and bigger.
As the planet grew, it wasn't very warm. Its warmth was probably around identical to boiled water that is 100 degrees Celsius. But now the interior of the planet has a very high warmth. It is presently so heated to molten rocks that run from volcanoes into fiery and dangerous streams of lava.

What is the reason for the heated earth? There were seemingly several analyses for the warming of the growing earth. The element from which the planet is formed includes radioactive elements like uranium. These elements produce heat-enough, in particular, to store the axis of the planet as burning as like this presently. This might show to tell how the lining of the green solid earth grew molten. But the examination of rocks reveals that the melting occurred more promptly than can be justified by radio-activity solely.
As the new earth grew, solid particles controlled to rain down against its surface. The force of all would have generated a tiny heat- just maybe to heat the globe so that the interior started to melt. Next, enough energy can be gained by the radio-activity to control the internal warm when the attack of particles are halted.
THE ORIGIN OF THE MOON
The development of the moon was a calm process that did not disturb the creation of the young earth. Scientists believed that the earth was the birthplace of the moon. A few of them implied that the Pacific Ocean surfaced that hole existed the times when the moon moved to another place and departed our young earth. Yet, the Apollo moon travel reconciled this thought. The moon acts distinctively almost from the planet to reveal that it wasn't a part of our earth. The moon stays on the alike lifespan like the earth which is about 4,600,000,000 years. Therefore, it was probably created as an isolated body like our planet and the separate planets, simply to be caught next on earth.

Mars apparently captured its pair of moons, yet is likely similar to the four giant outer planets formed their private moons. This must happen to any of them near much alike the process as planets held themselves developed, from the origin of a cloud of gas and dust.
Alex Halliday from the University of Oxford stated:
"The oldest rocks on the Moon were these white anorthosites because this mineral is not very dense, it normally floats on molten magma, so it would have been found close to Earth's surface rather than deep inside.

HOW UNIQUE IS OUR PLANET EARTH
There are numerous vapors of gas and dust spread everywhere in the universe. Scientists understood that both stars and planes are progressing beyond just like the solar system created long ago. They also assumed that separate planets with an unusual life form should exist about far away within the universe.
It is difficult to imagine the numbers of planets that carry life. But in the situation, you might think that the earth is a unique one among creations. Remember: the earth is the only one that rotates the sun. The sun is one of the 100,000,000,000 stars. The Milky Way (Galaxy) is its great island of the stars.
Astronomers conclude that there are 1,000 stars with their own planets they can detect easily. However, only the nearby stars can be caught. Possibly, astronomers believed that every star inside the Galaxy has planets. Though it's not satisfying to consider more roughly, our various powerful telescopes have the capacity to determine the extent beam of 1,000,000,000 galaxies towards the universe. Consequently, the complete counting of planets within the universe are apparently multiple millions.
