Humans can't breathe underwater. Chemically when hydrogen and oxygen gases combine we get liquid water. Oxygen is bound to two hydrogen atoms in water and so we cannot breathe .
then raises the doubt how do fishes breathe? Fishes have the capacity to remove the dissolved oxygen through their gills. But human lungs do not have this capacity.
