The temperature at and near the surface is greater than 0° Celsius (freezing point of pure water), and lower than 100° Celsius (boiling point of pure water). The atmospheric pressure is high enough to maintain the effective boiling point below the maximum surface temperature (about 67° Celsius), up to an altitude of at least 35,000 feet. There is also a volume of water far greater than the water vapor capacity of the atmosphere at average temperatures.
the inhabitants could have special adaptations, such as fish have gills that allow them to breathe under water.
The Earth continues to exist because of MATTER CYCLING, ENERGY AND GRAVITY
Water... and a climate that will allows it to exist simultaneously in 3 forms: Liquid, Gas, Solid
If water did not exist in all three states—solid, liquid, and gas—across Earth's temperature range, life as we know it would be drastically altered. Many biological processes, such as cellular metabolism and nutrient transport, rely on water's unique properties. The absence of liquid water would eliminate oceans, rivers, and lakes, severely disrupting ecosystems and climate patterns. Additionally, the lack of water vapor in the atmosphere would hinder weather formation and temperature regulation, making Earth inhospitable for current life forms.
The Sea of Tranquility does not exist on Earth- it is a terrain feature on the Moon.

could water exist as a liquid if we don't have a atmosphere
Water could exist as a liquid on Earth without an atmosphere in specific conditions where the temperature and pressure allow for liquid water to form. However, without an atmosphere, these conditions would be less stable and water would be more likely to evaporate or freeze quickly due to the lack of atmospheric pressure and insulation.
the inhabitants could have special adaptations, such as fish have gills that allow them to breathe under water.
Earth's moderate temperature range and its atmosphere with a stable pressure both contribute to the existence of liquid water on its surface. The temperature range allows for liquid water by maintaining conditions suitable for it to remain in its liquid state, while the atmosphere helps to stabilize those conditions by preventing water from evaporating into space.
Characteristics of objects in our solar system that allow life to exist include the presence of liquid water, a stable atmosphere, and suitable temperatures. For instance, Earth has a unique combination of distance from the Sun, which maintains a temperate climate, and a diverse atmosphere that protects against harmful radiation while providing essential gases. Additionally, certain moons, like Europa and Enceladus, may harbor subsurface oceans that could support life, highlighting the importance of liquid water as a key factor.
Earth is just the right distance from the sun, receiving just enough energy to allow liquid water to exist on the planets surface. If earth were a little further away, then the water would be frozen as ice, while much closer and the water would boil away as water vapour. Liquid water is essential for allowing life to exist.
Water can exist in three states, liquid, vapor and as a solid. On the earth, it exists in all three states.
Liquid water.
liquid, solid, and gas :)
