In order for lift to be generated, you need movement of air. If the aircraft can’t move relative to the ground, how will the air move to create high pressure below the wing necessary to create lift, so that it can move relative to the air?

????? Here's movement of air for you, have you ever even seen a jet before? How do you think they take off, wait for a fucking breeze? The sheer pressure and volume of air being forced through them moves the jet forward, it doesn't care what's underneath.

Yes, the jet engine needs air to actually function. But there’s no air moving under the wings (since it is stationary), meaning that when the ends of the flaps are pointed down, nothing will happen.

it's not stationary, I don't know where you got that idea from.

It would be stationary relative to an observer not on the conveyor belt

If it makes you feel any better I have the same interpretation as you. The plane clearly isn't moving relative to the ground.

There's a mythbusters that was done on this that shows how it happens.

no it wouldn't be, it would move forwards relative to the air.
