Lift is due to the change of momentum of the airflow over the wing. The wing can be on an A350, or a tea tray with an angle of attack, or a piece of smooth or rough balsa wood.
The effect of the wing is manifested in changes in the air flow's speed and direction that extend for at least about a chord's length above and below the wing, and can be approximated by the circulation theory description.
The total force on the wing is consistent with Newton's rate of change of momentum derived from the velocity field of the wake, and can be resolved into components both up and back, giving lift and drag respectively.
Along any streamline, Bernouilli's equation holds too, if you take care at shocks.
The ratio of inertial to shear forces, diagnosed by the Reynolds number, controls whether/how-quickly turbulence builds up in the flow near the wing, and whether you can model it in a wind tunnel of a specific size, operating at a certain speed and density.
The compressibility of the air affects how shocks (sharp changes in the air's speed, density, pressure and direction) form in the supersonic air above the wing at high speeds.
Individually, none of these elements gives a complete picture of how the air moves as the wing passes and the effect it has. Their interplay is required to describe and understand what happens.
Mr Tullamarine is absolutely right though - you probably need to know how it works, rather more than why it works, and to tell whatever suitable story keeps in your mind how it works.
