Gravity and Temperature
Water can exist as a solid, liquid, and gas on Earth due to its varying temperatures and atmospheric conditions.
The Earth is the only planet to have water in a liquid state because it is neither too close nor too far away from the sun. If it was too close, the sun's heat would vaporize the water . If it was too far away, the water would be frozen solid.
Among the planets, only on Earth there are conditions of pressure and temperature for water to exist in all 3 phases.
the presence of liquid water on Earth's surface, which enables life to exist. Other planets in our solar system are either too hot or too cold to support liquid water on their surfaces, making Earth unique in its ability to sustain a diverse range of organisms.
Earth is the planet that is approximately 150 million km (93 million miles) from the sun, which allows for water to exist in solid (ice), liquid, and gas (vapor) states due to its moderate temperature range.

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.
Water can exist in three states, liquid, vapor and as a solid. On the earth, it exists in all three states.
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.
Liquid water.
solid liquid gas
liquid, solid, and gas :)
Water can exist as a solid, liquid, and gas on Earth due to its varying temperatures and atmospheric conditions.
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
