How airplanes fly

For a long time, the way that airplanes worked was confusing and I had no idea how those giant bulky metal tubes were able to stay in the sky, but I recently found out how they actually fly. The creators of the wings make it so that the top of the wing is more rounded while the bottom is relatively straight, so the air that must go over the top must move faster than the air on the bottom must. And, when the air is moving faster, the pressure there must be lower, then the pressure is lower on the top of the wing and higher on the bottom and because air likes to travel from high pressure to low pressure, the air then pushes the plane up and these forces can be adjusted based on speed and altitude and the angle of which the wing is turned, and all of these things combine to create a flyable plane. This picture explains it better than I do.
