All water, even rain water, contains dissolved chemicals which scientists call "salts." Some scientists estimate that the oceans contain as much as 50 quadrillion tons (50 million billion tons) of dissolved solids.
If the salt in the sea could be removed and spread evenly over the Earth's land surface it would form a layer more than 500 feet thick, about aw salts from the land. In fact, since the first rainfall, the seas have become saltier.
Most of the ocean's salts were derived from the breaking up of the cooled igneous rocks of the Earth's crust by weathering and erosion, the wearing down of mountains, and the dissolving action of rains and streams which transported their mineral washings to the sea.
so you are saying ( for now ) all ( or at least “most” ) of that salt in the ocean was NOT put there by a god but came from natural processes. Well, providing you stick to that ( which you will not ) , that is at least more consistent than what tim88 says who continually first says it comes from natural processes and then says “God did it” and then back again.
BUT, it would have taken at least 100 million years for so much salt to accumulate to its current concentration via all those natural processes. Therefore, if you are saying all ( or at least “most” ) of that salt in the ocean was NOT put there by a god but came from natural processes as your first principle, then the fact that there is so much of it in the oceans logically should be proof to you that the oceans and therefore the Earth is at least about 100 million years. But is apparently doesn't prove to you this! Why? Because you are illogical.
Salts become concentrated in the sea BECAUSE the Sun's heat distills or vaporizes almost pure water from the surface of the sea and leaves the salts behind. ( my emphasis)
what? In all the oceans? If so, you do know that when water evaporates it doesn't simply cease to exists but turns into water vapour -right?
And that water vapour doesn't just cease to exist but is trapped in the Earth’s atmosphere until it eventually falls back down as rain -right?
And that rain water goes back into the sea -right?
That is what the hydrocycle is: http://water.me.vccs.edu/hydrocycle.htm
so, except of a few small seas such as the dead sea etc that are partly isolated from the main bodies of ocean water, “Salts become concentrated in the sea BECAUSE the Sun's heat distills or vaporizes almost pure water from the surface of the sea and leaves the salts behind.” is clearly FALSE because any water that evaporates that way is simply returned back into the ocean via the hydrocycle to dilute down the salt concentration back down again and thus evaporation cannot explain why “Salts become concentrated in the sea “ as you claim above for all the oceans.
