This is exactly the reason why pressure is build up underneath the wing (pushing the airfoil up on air molecules == force).
No, not really. See: http://www.av8n.com/how/htm/airfoils.html#sec-consistent
Try this for a start:
An airflow over the wing is causing the downwash at the end of the airfoil. The airflow below the wing is now kind of captured between the airfoil and the layer(s) of air underneath itself.
In this situation it can go in just two directions, up or down, The majority of the flow will go down, bu a tiny fraction of the molecules has to go up. If the number of molecules that go up is high enough it will lift the airfoil up with it.
This is really what DaVinci already had discovered back in 1530-something.
