...And it is the most abundant. It’s everywhere...

Only on the surface. The 10 most abundant elements on earth: https://education.jlab.org/glossary/abund_ele.html Hydrogen comes in at number 10 with 0.14%. While Oxygen is number 1 at 46.1%. Since water is H2O water is way down there on the abundance list.

Water its just less dense than most of the things the earth is made of and floats to the surface.

Really? It just floats to the surface? Fifteen minutes from where I live are The Pine Barrens of New Jersey. Underneath the Pine barrens, according to the experts is one of the largest underwater aquifers in the United States. It's estimated there is some four trillion gallons of fresh water sitting below the soil in The Pineys.
