Differentiate between the earth and other planets in general?

Answer 1

The biggest difference between Earth and the rest of the planets is that the Earth is in the "green zone", which is the range of distances from the sun where liquid water can exist. Too much closer to the sun and our water would vaporize. Too much further, and it would freeze. We're just in the right spot, and I don't need to tell you how important water is to the formation of life!

Answer 2

The Earth is the only known planet to support life due to its unique combination of atmosphere, temperature, and water. Other planets in our solar system, like Mars or Venus, have different atmospheres, temperatures, and compositions that make them unable to sustain life as we know it. Additionally, Earth is the only planet with significant surface water in all three states: solid, liquid, and gas.
