Water, correctly applied heat, vegetation and oxygen; at least that is what most animals need.

The planet Earth doesn't need life; and especially humans are a danger for the Earth.
There are no "life conditions" on the Moon, an arid, airless body completely devoid of any sign of "life as we know it". The only time that the Moon will be habitable is when we build an artificial habitat capable of holding in the air that we need to breathe. Earth, on the other hand, is ideally suited for us - or perhaps it would be more apt to say that WE are ideally suited to the EARTH. We evolved here.
Life has been found in extreme environments on Earth such as deep-sea hydrothermal vents, acidic hot springs, and frozen Antarctic lakes. These organisms have adapted to thrive in environments that were once thought to be inhospitable, suggesting that life may be more resilient and adaptable than previously thought. Such discoveries expand our understanding of the potential for life to exist in a variety of conditions, not just those considered "Goldilocks conditions."
Life on Earth is adapted to Earth's specific conditions such as gravity, atmosphere, and temperature, while life in space would face challenges like microgravity, radiation, and vacuum. Life on Earth has evolved over billions of years to thrive in its environment, whereas life in space would need to adapt through technology or genetic modifications to survive.
Earth's habitable zone is limited to a narrow layer near the surface because this is where conditions are optimal for life to exist. Factors such as temperature, pressure, and the presence of water are crucial for supporting life as we know it. Beyond this narrow layer, conditions become extreme and inhospitable for most forms of life.
Life has been found in extreme environments such as hydrothermal vents deep in the ocean, acidic hot springs, and ice-covered lakes in Antarctica. These environments challenge the traditional understanding of habitable conditions, showing that life can thrive in extreme temperatures, pressures, and chemical compositions. This suggests that life forms may not always need the "Goldilocks" conditions typically associated with habitable zones.
The troposphere is the lowest layer of Earth's atmosphere where the air is densest and contains the majority of Earth's weather. It is perfect for life on Earth because it contains the oxygen we need to breathe, shields us from harmful radiation from the sun, regulates the planet's temperature through the greenhouse effect, and provides the conditions necessary for precipitation, which supports plant and animal life.
Earth is special because it can sustain life, it has all of the conditions things need to live. Other planets may contain life but as far as science knows, no because the conditions aren't correct for life...Most plants don't have any type of water for life or some resource of food and the air surrounding the plants aren't good for you.
it needs the sun, the ozone layer, air, and water for it to survive.Earth has liquid water and suitable temperature range and atmosphere for living things to survive.
