The history of our species is about who has had enough water, and how those people have successfully used it to their benefit.

True?

In part, yes.

It is an over simplification of a story which is much more complex, but you can apply this rule to most cultures and times, and make a lot of valid arguments.

New York Yankees? More water.

Celtics of the past, like UCLA back then, too?

Lots of H2 O.

Dynasties have more and better use of water.
