we can't fly in air by attaching wings because

t put into practical application an aerodynamic concept known as "upper surface blowing." (See Page on nasa.gov) This did almost exactly what you're suggesting (except for hovering), with a bonus in terms of predicted noise reduction: "[The] engines are mounted above the wing, which seems to be beneficial, because the major part of the engine noise is shielded by the airfoil. The whole engine exhaust is blown over the wing and thus the flow over the flap can bear large adverse pressure gradients without separating." (https://www.tu-braunschweig.de/M...) The net effect of this was to allow for very short field takeoffs and landings.
Give yourself kudos for inspiration/intuition! For my part, this whole principle seems almost like lifting yourself up by your own bootstraps or Blowing your own sail? That's why I like helicopters; I can see the twirly thingies that hold me up.
this is because:-
Even if we had wings are bone weight is still too, much for our wings to hold. Unlike birds.
