"not because they have an airfoil."

This is wrong, anything placed in airflow can generate a certain amount lift and become an airfoil - do some research. The simple principle behind this is that it is indeed "flying" or "moving forward" relative to the air around it. There's no magic behind it. Pretty neat I must admit.

But remember anything in flight only has to do with the relative airspeed around the lifting body (or wing)
