The difference between fresh and salt water arises from the climate cycle.
Water rains onto the land - hills and mountains - and runs to form rivers that flow to the sea. This water dissolves very tiny amounts of minerals from the rocks it flows over - so little that it remains to all intents fresh (though you will know that some water is hard because of dissolved minerals).
When it reaches the sea evaporation takes over to return water to the atmosphere. Evaporation leaves behind the dissolved minerals - only the water evaporates.
Hence the minerals concentrate in the sea, while the water that falls on the land is always fresh.

Millions of yers ago when the earth separted from the sun, it was very very hot. Then there was a time other molecules got formed. When hydregen and oxygen got formed to become water maolecules, the earth was so hot it became water vapour instantly. Then there was a time more water vapour got formed and occupied the whole atmosphere with the earth still hot. As the earth slowly cooled down, there was a period when the whole earth was in the cycle of water evaporation and precipitation( rain ) and again evaporation. This incessant rain washed away minerals into a primoidal soup, on the earth to what we call occeans now. This conentrations of minerals and salts in the (primoidal suop) which became occean (water) is responsible for the occeans to be salty.

During formation of earth (cooling down process), rain fell for along time. Chloride element from volcanoes was brought down by water and chemically reacted with Sodium element of rocks. This mixture (Sodium Chloride) makes the sea water salty.

No it is just natures way of handling those bad chemicals .
Example
HCL very bad acid.
Caustic soda bad base.
Mix together to a PH of 7 and what u have. ?????
Nothing but table salt and water.
