Fish need water flowing over the gills to extract oxygen, if the gills become dry, the fish dies.
Interesting bit of info: The warmer the water, the less dissolved oxygen there is. If you see your fish gasping at the surface, first thing to check is the air pump. The very next thing is the water temp.
72-78 is ideal for most fish, unless you are keeping discus. They need temps much higher. Around 85. Goldfish are cold water fish and need temp in the mid to low 60's.

Fish need water and special organisms inside the fishs' gills provide oxygen for the fish.

The gills "rake" dissolved oxygen from the water. I guess as long as you had a constant oxygen flow past the gills a fish could live but a fish's instinct tell it it needs the water.

Yes... fish need to live in water... but the gills take oxygen out of said water so yeah.

Other than fish like bettas, and gouramis which get their air though other means. Fish get oxygen though their gills which need water to function. A fish will suffocate in a matter if minutes if it's not in water. Fish like bettas which don't need gills to get oxygen will survive until they dry out, or die of stress.

The writer "8inthecorner" is absolutely right and has provided a very good answer. For gills to work they need water.
But the water must contain dissolved oxygen (O2).
Different fish have different needs - both for amounts of dissolved oxygen and optimum water temperature. Although lower water temp allows the water to 'hold' higher levels of dissolved O2, cold water is of little use to warmwater species such as tropical fish. The reverse is also true, too warm water can be fatal to coldwater species - both because of the temp and because of the reduced O2-holding capabilities.
More about different O2 requirements: Trout for example prefer cooler waters and need O2 levels of 10 parts per million (ppm)or higher. The common Sucker on the other hand can survive with warmer temps and O2 levels as low as 2 ppm.

Fish need water to pass across the gill to remove oxygen. also the fish begins to dehydrate when it is out of the water.

the fish needs water
the gills work to extract oxygen out of the water
it can survive for a little while out of water but it will die

The gills pull oxygen from the water and discharge carbon dioxide to the water. But they can't do it dry.

fish require water in order to extract oxygen to breathe as they have no capacity to extract oxygen directly from air. Gills are required!
