'coz water can exist as liquid at 1 atm and room temp.

Water exists as a liquid on Earth because the atmospheric pressure and temperature is right for it to. If the pressure was lower, water would exist as a gas (water vapor) if the temp. was lower it would exist as a solid (ice) which of course it does in some places. I'm sure there are planets where water is never liquid and exists normally as solid or gas all the time.

Usually water is in liquid form between the freezing and boiling point.
The overall temperature of the earth is just within this range.
Therefore, water can exist as a liquid on earth.
As for the reason of the nonexistence of liquid water in other planets, the temperature of those planets are rather extreme - either really freezing or really flaming.
Thus, either the water is not on the ground OR the water is frozen.

I can't answer this completely. Water molecules have intermolecular hydrogen bonding. At room temperature, the molecules are mobile yet hydrogen bonding is still present. Water can be a liquid on earth.

Because it's there.
