And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. Genesis 1:10
"The salinity of our oceans can give us a ‘clock’ of sorts, because we
are able to estimate the amount of salt entering our oceans as well as
the amount that leaves. 
It turns out that much more is entering than
leaving, so the oceans are getting saltier over time. So let’s use this
as a uniformitarian ‘clock’ by assuming the processes have stayed much
the same. Starting with fresh water, how long would it take for the
oceans to become as salty as they are?
A study by creation scientists Steve Austin and Russell Humphreys,
using the most conservative numbers available, gave an absolute upper limit (not actual age!), of 62 million years.
----While this may seem like a long time, it is actually far too low a
number to accommodate the secular age for the ocean of 3.8 billion
years.
And note that the oceans would have started out with some salt in them,
plus a stupendous amount of salt and other minerals would have been
added during the Flood from erosion and volcanism.
More recent estimations show even more salt entering than Austin and
Humphreys accounted for, meaning the estimate should be even lower.
---- Simply put, the oceans should be much saltier than they are 
today if
they were anywhere near as old as the secular timeline claims.
The only
‘out’ for long-agers is to assume that the rates have dramatically
changed—which undermines the whole idea of uniformitarianism!" CMI
