Why is that water is needed to live as opposed to alternative liquids? If coffee is just bean-flavoured water, why couldn’t you survive by only drinking coffee? If you were lost on a desert island and had only coffee, juice or soda to drink, could you survive?

You don’t necessarily need plain water, and plenty of people go long periods without ever drinking it. It may not be as healthy, due to the sugar content of soda and juice, or caffeine in coffee, but they will satisfy the body’s water needs, in addition to the water taken in from foods. And while caffeine is a diuretic, drinking coffee still provides a net increase in hydration.
