Where do fruit flies come from? How do they just appear when there is fruit left out?

Fruit flies come from eggs that were laid by the fruit flies before, which also hatched and were fruit flies before, etc.

I don’t know, maybe they just randomly jump from the air into the fruit? Or maybe the fruit is the only thing they’ll eat? How could I know?
