And if theologically human goes that far back...
I recall reading some time ago about evidence that the Strait
of Gibralter has opened and closed several times in the past,
sometimes closing long enough for the Mediterranean basin to
mostly or completely dry up. Unfortunately, I don't recall how
long ago the last of these episodes was. Perhaps remains of the
civilization that "needed killin'" are below the current sea level
in the Mediterranean basin.
