History
Earth's history is a subject that spans millions of years. It is believed that our planet was formed about 4.5 billion years ago as a result of the Big Bang, which formed its chemical composition and the layers of the Earth's crust. Then, before the first microscopic organisms began to appear, a subduction process led to the formation of the first continents. Millions more years of evolution led to the formation of complex life on our planet. Today, Earth is home to billions of people, plants, animals and other forms of life.
