The Earth is not too far and also not too close.
The presence of water is a key factor that makes life possible on Earth. Water is essential for various biological processes, acts as a solvent for biochemical reactions, and helps regulate temperature. Additionally, Earth's distance from the sun and its atmosphere also play crucial roles in creating conditions suitable for life.
It's distance from the sun, its magnetic shield, it's abundance of liquid water. Take your pick.

The suitable temperature range for the development of life on earth is different from the suitable range once life has developed. Once life has a strong foothold, evolution allows life to adapt to both increasing and decreasing temperatures, until it is able to survive in extreme environments at both ends of the scale.
The atmosphere is located right above Earth. Or the circle around Earth that protects it from all different kinds of things. And makes life on Earth suitable for living.
Earth is able to support diversity of life: It has the suitable atmosphere which is made up of different gases. It has a moderate temperature as it is not to far and not to close to the sun. It has the a suitable amount of water covering 2/3 of the Earth's surface.
