what the heck is lift?

Gone,

Lift is created by the differing pressures between the upper and lower
surfaces of the wing coupled together with AOA.

I'd say it's the other way around: Lift creates the pressure differential.


Wings generally tend to have a curved suface. The upper surface has a
greater arc or curvature than the lower surface. As the air flows across the
surfaces of the wing, the upper surface air is forced to move faster than
the lower surface air thus causing a pressure difference between the two
surfaces.

Forced by what? And how does your "theory" explain inverted flight? I don't
buy it.

BTW, this has been beaten to death in countless aviation newsgroup
discussions. I once thought like you, because I was taught that way. It's
still a bad theory. I suggest googling. Keywords might be: lift, flight,
Bernoulli, Newton.
