The oceans and seas have been salty for a very long time. As soon as rain began, it would rain on land and the water would dissolve salt from the earth which would run back to the sea. Then sea water would evaporate leaving the salt, and creating more rain. This process repeated itself over eons of time, making the oceans salty.
Hydrothermal vents and volcanoes below the surface of the ocean also contribute salt.

How is salt made from salt water?
Salt isn't made from salt water, it is already present in the salt water. If you were to heat up the salt water, or put it on an evaporating dish, after a while, all the water will be gone and you'll be left with salt crystals. Industrially sea water is 10times concentrated to get salt crystals.
Where is salt water made?
Salt water is obtained by dissolving sodium chloride in water.
Is salt water made of 1 or more molecules?
It is made of water (H2O) molecules and salt (NaCl) molecules. So two different types of molecules.
Which ice cube will melt faster one made of salt and water another made of sugar and water or one made from just water?
The ice cube made of salt and water will melt faster than the one made of sugar and water, which in turn will melt faster than the one made from just water. Salt and sugar lower the freezing point of water, which causes the ice to melt faster.
