This argument is false. Superman's flight would be more like a bumble bee if you wanted to use an Earthly example. Planes fly due to the differential between are pressure about and below the wing. This is called lift. Superman does not have wings or any kind of gauzy winglike appendage like a glider, so therefore his flight is not due to lift. Bumble Bees defy physics in their flight for the same reason, their mass wing span ratio is way too low to allow for lift. Neat huh?

Flying mean zero gravity, there is impossible zero gravity on earth. He look like float but not flying like bird. Actually i think the super hero really look stupid but i enjoy the story.

It really depends on the story you chose. The original origin of Superman had him as made of denser material than humans. This account for his resilience(Not hurt easily) and if he is more dense gravity actually has a stronger pull on Superman than a human, since the force of gravity is a relationship of mass and distance. The original Superman could only leap tall buildings, not actually fly. Later on, Around the time of Crisis on Infinite Earths or a little later I think, Superman's powers were redefined as merely being a force of will. He can do it because he believes he can. Any more recent than that I really don;t know.
