For example
Water molecules are polar and attract each other like magnets. They are also attracted to each other by hydrogen bonding. There are other liquids besides water such as grain alcohol, rubbing alcohol, gasoline, benzene, olive oil and mercury. If you dip your finger into a pool of mercury your finger comes out dry. Dip a candle into water and it doesn't get wet. The molecules don't bond. They are not attracted to each other. Wetness is a relative term. Some liquids are wetter than others. Water isn't a very good wetter as liquids go. Alcohol is much better than water as a wetter. All liquids aren't wet and even water is sometimes dry.
My oh my what you can find out when you ask Google a question.
So the answer to "why is water wet" is complicated.
