What makes the Earth unique?

Unlike the other planets of our solar system, life developed into many forms on the Earth after its emergence. Liquid water and oxygen for breathing made this possible. Millions of species of plants and animals thrive today on land and in water. Water covers more than two-thirds of the Earth’s surface. Therefore, the Earth appears blue from the moon or from the International Space Station. For this reason, it is also called the ‘blue planet’. Till now, scientists have not discovered life in any other place in the universe, but they believe that one day they will do so.
