AND fish can still drown in water( ie not be able to get any oxygen to breathe)
Water only has a limited amount of oxygen( breathable oxygen) in it. If a fish is caught in a net and is not able to move, then it depletes the oxygen in the water around it. Fish have to move in water all the time, in order to get oxygen into their gills. If a fish gets below 1.0-2.0 mg/L oxygen in water it will Die.
The oxygen in the air on this planet is decreasing. That shouldn't be IF ACCORDING to your logic, since there is oxygen in water. In fact oxygen is one of the most common elements in the earth's crust. But that oxygen is bonded, and thus NOT ABLE to escape its bonds and become Oxygen in the gaseous form. WE DO not get oxygen from water itself, the oxygen in the atmosphere is the oxygen( that we breathe) that is not bonded to anything else, oxygen that is dissolved in water, and those produced from plants.
Dissolved is not a bonded. You can dissolve sugar in water and still get back the sugar after the water has been evaporated. You add water to clay to get pottery. After firing, there is no way ( easy way, that does not involve massive chemical infusions) to get that clay back, the way it was. What happens there is that the clay loses its chemically bonded water, and once the chemical bond is gone, its gone.
Have you any idea how much energy is required to break the bonds of a single Water molecule???? Last time I checked, you need temperatures of over 850 celcius and catalysts. The last time the earth was that temperature on average was several billion yrs ago.That type of energy does not exist on the earth's surface naturally anymore. The only way it can be done is by chemical means.
And as God was here first and created everything, I guess Aristotle used God's idea and had everybody think he was so brilliant.
OF course it was there first. Aristotle did not come up with it, he just identified it. Just like Newton and gravity, it always was there, its just that they identified it and went on to find out more about it. NOW that is God's work at one of it's best. God gave us advanced brains to think and BY GOD those men sure did use it.
