About 4.6 billion years ago, the Sun, Earth, and other cosmic bodies in the solar system formed from clouds of gas and dust orbiting space. Earth's conditions - poisonous gases, the harmful rays of the new sun, strong storms, volcanoes and earthquakes - have made life on our planet impossible. But she gradually began to cool down and calm down. Thus, about 3.5 billion years ago, early life forms appeared. They were microscopic, jelly-like dust in the middle of the sea. Living things remained small in size and simply built for another 2 billion years. However, they changed the conditions in the air and water. About 1 billion years ago, this finally allowed larger organisms to thrive and thrive. Initially, they were mostly plants that thrived on solar energy. 540 million years ago, there was a rapid "explosion" in the animal kingdom. The creatures became larger and more complex in structure, began to eat new plants, as well as to eat each other. The changes have continued ever since, and life on the planet continues to adapt to the constant changes in the natural environment and environment.
