because it is the right distance from the Sun that liquid water can exist on its surface and it's massive enough that it can maintain an atmosphere.
They don't, so there is no "because".
It so happens that a variety of natural forces have Earth's temperatures be different things at different times. Life either adapts to this or it does not. Sometimes it does not.
Flagged - much more detail is required - for example, we need a moon about our moon's size, we need the right elements, we must have the right type of sun, a planet like Jupiter to clear out stray asteroids, etc, etc; the list for the "Goldilocks" zone is very long.
The three conditions that make life on Earth possible are: presence of liquid water, suitable temperature range, and presence of a stable atmosphere with oxygen.
Life can exist on the Earth's crust, which is the outermost layer where conditions are suitable for life to thrive. This layer includes the continents and ocean floors where organisms can survive and thrive.
Presence of liquid water: Water is essential for life as we know it, serving as a solvent for biochemical reactions. Suitable temperature range: Earth's distance from the sun allows for surface temperatures that support life. Presence of an atmosphere: Earth's atmosphere provides the necessary gases for respiration and protects life from harmful radiation.
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.
The greenhouse effect is the process that allows Earth's temperature to remain within a suitable range for life to exist. Greenhouse gases like carbon dioxide and water vapor trap heat in the atmosphere, preventing it from escaping into space. This helps to maintain a stable climate and temperature on Earth.

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.
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.
At the moment, as far as we know, the only planet suitable to support a diversity of life is our Earth.
Because there is Oxygen, suitable amounts of Carbon Dioxide, and enough H2O to support life.
