'wet' means saturated with water particles [e.g. a wet rag]
at the microscopic level the water particles have surrounded and weaved between the rag. water is a physical change, not a chemical change, the only real criteria being it having to be surrounded by water particles.
water particles obviously touch each other. if you have a glass of water, one of the water particles floating around in that glass is surrounded by other water particles, hence making it [by raw definition] wet.
same goes for the particle next to it, and the particle next to that one, and the particle 10,000 particles down the line, and the particle sticking to the side of the glass; it is enveloped by a multitude of water particles from most or all sides, making it 'wet' on the molecular level
now if pretty much every water particle in that glass is wet then the entire glass of water is wet
therefore water is wet on a collective level BECAUSE it is wet on a molecular level
apply this to any body of water even aerated water and it still applies
it really isnt that much of an argument if you put a little science to it
