Scientifically speaking dinosaurs extinction was the absence of wings?

Apparently dinosaurs could not wing it the survival skills, so only their descendants the birds could accomplish such task , like mammals , birds are warm blooded, but contrary to mammals the birds structure of bones are aerodynamic , something that dinosaurs could really not accomplish specially with the gigantic bodies , besides a few exceptions of aquatic monsters , dinosaurs in generally were not able to swim , scientifically speaking , we want to believe the dinosaurs were warmed blooded but we have no evidence at all specially in the fossil record , aquatic mammals or birds have an extraordinary hydrodynamic organism well adapted to their environment , been unable the dinosaurs to fly or swim in the event of universal flood cause by meteorites or the end of an ice age the extinction of dinosaurs was irreversible , so not only they disappear , but they have no place in the ladder or evolution tree unless you have allot faith in evolution it self
