Gravity and Temperature
The atmosphere and water. The atmosphere holds oxygen that people need to survive and it also helps protect life from overheating and from harmful UV rays that come from the sun. Also, water is an essential aspect to life and without it, we wouldn't be able to survive.
Earth is a distance from the sun that allows for an overall temperate climate that allows for the existence of liquid H2O. It also has an atmosphere and gravity that keeps the existing water circulating back to the surface.
what two characteristics of earth allow liquid water to exist
Among the planets, only on Earth there are conditions of pressure and temperature for water to exist in all 3 phases.
We wouldn't know because if space didn't exist earth wouldn't exist and if earth didn't exist we wouldn't exist! So there you go there is your answer.
It is too cold for liquid water to exist on the surface
Why scientists believe a liquid water ocean might exist on the moon Titan
The moon doesn't have water but it's 93 million miles away. So since the moon orbits the earth I guess the answer is...The earth.
-Gravity (so it doesnt float away) -Temp (not too hot or cold)

the inhabitants could have special adaptations, such as fish have gills that allow them to breathe under water.
could water exist as a liquid if we don't have a atmosphere
could water exist as a liquid if we don't have a atmosphere
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.
liquid, solid, and gas :)
solid liquid gas
