Why do birds fly in the air with wings?

Explanation:

A big part of the reason birds are able to fly is because their wings create airfoils that can split the air. We also find airfoils in the shape of tiny wings on bugs or huge wings on airplanes. However, human arms are not good shapes for airfoils. As you've observed, even if you try to flap, you won't fly.
