Have you ever noticed when you are in the shower that the shower curtain keeps moving inward towards the stream of water? That's because the moving water creates an area of low pressure. The high pressure on the outside of the curtain moves toward the area of low pressure which moves the curtain inward. If you light your bic and blow to one side of it, the flame will move to that side towards the air stream. Same reason.
Same with a plane wing. The assymetrical shape of the wing makes the air moving over the top of the wing move faster than the air moving across the bottom of the wing. So, the air pressure on top of the wing is lower than it is on the bottom. The air on the bottom, then, moves towards the top and pushes the wing up as it does.
