How was the Earth Made?

You might wonder how the Earth was made? Yes, the planet that we live on, how is it made? There are a lot of theories on how it was made but here is the scientific theory on how it was made. The formation stage of the Earth is when the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to   become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust. The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young hot sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon. 

Some people say a huge explosion, known as the Big Bang, then sent matter and energy expanding in all directions. This Big Bang hypothesis led to more testable deductions. One such deduction was that the temperature in deep space today should be several degrees above absolute zero. Observations showed this deduction to be correct. The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things. Some people think why is the planet we live on named Earth and why could it have been a good and cool name? We have no idea who first penned the name Earth for our planet, nor do we know exactly when the name came about.
