Look at the bird flying and soaring in the sky. The Wright brothers tried to emulate this. Note the flight of the birds. Lift is caused by the curvature of the wings. Air flows faster over the upper wing as it has further to go. As air moves, pressure is reduced. You see this driving with a window open. Note that it is harder to breathe.
