Why is the earth is the only planet that has life?

Answer 1

Earth is a great planet because, Earth is just right where it is, if Earth was closer to the Sun then it would be too hot and the water like lakes and oceans would boil and there will be no water.. But if we were farther away then it would be really cold to live on Earth.. We are living on Earth because it is just right to be living on it.

Answer 2

There is life due to the following reasons:

1) Atmosphere: Our atmosphere has the correct thickness to filter the harmful UV radiations from the Sun.

Although not essential for all life, oxygen is important for much of the life on Earth.

3) Liquid surface water - Life started in water. It is a precious resource needed to sustain all life, as we know it.
