Eli5: why aren't there bodies of other liquids besides water on earth? Are liquids just rare at our temperature and pressure?

Pretty much. Water is special for a lot of reasons, in a chemistry sense.

The common gasses, Hydrogen, Helium, Nitrogen, CO2, Methane, etc... become liquid at very cold temperatures that we don't naturally experience here.

We have oceans of liquid rock and metal under the surface, because of the heat and pressure.

So then the question is, what other naturally occurring substance is liquid at approximately 300K and 1 atm?

While there are a few, there aren't any in great abundance. Not enough to make a geographic body of water. 

You probably know but there are methane oceans on moons in our solar system.
