Answer:
The Earth is the third planet from the Sun.
Step-by-step explanation:
The Earth is the third planet from the Sun, which is just the right distance for life to utilize the Sun's power and energy. Earth has two thirds of its surface covered by water and it is, up until now, the only planet to harbor life. It's atmosphere is rich in oxygen (which humans need to breath) and nitrogen. The sun's energy is crucial for Earth existence. Thanks to the atmosphere, the sun's energy reaches Earth attenuated. Otherwise, without atmosphere filtrating the sun rays and power, life as we know it wouldn't be possible.
