How was the first seaside community created?

Seaside communities developed because prehistoric humans
recognized the advantages of living close to water. Living close to the ocean was good,
and living close to the outlet of a river into the ocean was quickly recognized as being
even better. That's why ancient cities were so often built at naturally occurring
ports.

Water was essential for drinking purposes - even if
the water in the ocean was not good to drink, the water from a river flowing into the
ocean could be used.

That river water also provided a
source of food in the form of fish and in the form of animals that came to the river to
drink. When agriculture began, the farmers learned to water their crops, first by
carrying water to the plants and later through irrigation
ditches.

Water also provided an easier method of
transportation than carrying goods over land. As trade developed with groups living in
other locations, boats were designed and built to enable people to get from place to
place.
