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.
