Observation can lead you astray: and that is clearly the case here if
you actually think that air can *pull* on a surface.


Why can't air PULL on a surface? Air is made up of molecules.
Molecules have mass. Anything with mass can attract anything else with
mass, can't it?

Nope.

I'm making the point that the upper surface contributes absolutely *no*
lifting force.

None.

Zero.

In fact, it provides a downward force. Every time.



....and you are making the point that when you are breathing in, you are
not SUCKING air at all. It's atmospheric pressure on your chest that
inspires the air. Wow! Who would have guessed? :-)
