Hi Aby, I don't know the chemical composition of sea water but one thing is sure, the salty taste comes mainly from millenniums of decomposing creatures like seashells. Also the sand is mostly made of crushed shellfish.

All the rivers of the world flow into the sea, and they carry with with them the natural salt in the earth (sodium Chloride) and that has been happening since the the earth cooled down enough for rain to fall. The salts have been accumulating in the oceans since there were oceans.

Ocean water tastes salty to us primarily because of the Na+ ions derived from weathering of crustal minerals. All crustal rocks, particularly granitic rocks, are rich in sodium and aluminum relative to mantle rocks. Carbon dioxide is absorbed by surface waters, creating an acidic solution that chemically weathers the crustal rocks. Sodium-rich minerals such as plagioclase break down to form Na+ ions, which get carried via rivers to the ocean. The sodium concentration in the oceans is thought to have been roughly constant for the last 600 million years. Sodium is lost to the atmosphere, lost via sedimentation and removed by reaction with newly-created basalt at mid-oceanic ridges such that there is no accumulation of sodium in the oceans over time.

rain water erossion on land flowing into the oceans bring many minerals including sodium ( salt) The loss of water from evaporation does the rest. And it will get saltier too as time goes on, Just like the Salton Sea in Calif, and the Dead Sea in the mid east,, as well as the great salt lake in Utah.

Basically, the sea is salty because the rivers carry dissolved salts into the oceans. The water that evaporates and then forms clouds and then rain, does not contain salt. So the level of salt in the oceans is slowly increasing.
Scientists have done careful calculations to estimate the amount of salt entering and leaving the oceans.
If the oceans were originally salt-free, then it would take just 62 million years to become as salty as they are now.
This is one of many good indications that evolutionary timescales are false.

because the sea is made of salt
