Why does Earth support life?

• Earth may be the only planet in the solar system where life can exist.
• There are several factors that favor the earth's ability to support life, ranging from microorganisms to humans. Among the most important are:
• To begin, our planet has an atmosphere that contains several important gases, including oxygen, which is critical for life.
• Second, a large portion of the planet has favorable climatic conditions for life.
• Third, water is one of the most important elements for supporting life, as the first life on Earth began in water.
• Fourth, without the sun, there would be no earth; the sun is critical to the survival of life on Earth.
• Fifth, the presence of an ozone layer in the atmosphere is important; while the sun is essential for life on Earth, all of the sun's rays are harmful; the ozone layer protects the earth from these harmful rays.
