Question

Yet it tastes like nothing.

Answer 1

You need water to live. Organisms that “like” water are more likely to drink it, which means they’re more likely to live, which means they’re more likely to live long enough to have children, which means their children are likely to inherit that trait and “like” water. Repeat for long enough, and here you are.

Same reason salt tastes good (because you need it to live), and sugar tastes good (because it’s easily-accessible energy).
