Why is water tasteless? Since our bodies need water, shouldn't they have evolved to enjoy the taste?

The best other example I can provide is sugar. Our bodies use sugar to produce ATP and energy for our cells. Therefore, anything with sugar tastes sweet and delicious. So why don't we have the same craving for water?

taste didnt evolve to make us enjoy food but to help us distinguish what we are eating. If water had a taste you would be tasting it constantly, as your mouth is almost always wet. Water which is impure does have a taste which registers as either rancid, salty, bitter and so on.
