ELI5: Why does oil fry food and make them crispy while water boils food and makes it soggy?

Actually you've kind of answered your question right there.

Oil fries food and makes it crispy.
Water boils food and makes it soggy.

But oil that fries food does so at a *much* higher temperature than 100^o centigrade, the boiling point of water.  That sound you hear when you fry something?  That's the water boiling away out of the outside layers of the food.  Frying *removes* water from the food by boiling the water off.

You could accomplish the same thing by baking the food, but frying heats the outer layer of the food much faster than any other method, so the outside gets hotter faster, while the inside of the food stays cooler.  Cooler means moister interiors and hotter means cripy exteriors.
