Why do Humans refuse to admit that they are just a failed product of evolution?

It's just so frustrating as hell how Humans persistently refuse to loathe themselves and admit that they are just inferior products of evolution since they have such unimpressively frail bodies that are too physically inadequate for them to survive in a healthy natural environment without resorting to using their unnaturally bloated brains to invent all sorts of destructive technology, plus they have only been around for such a short amount of time while other animals such as the Dinosaurs have been around far longer and also evolved much more physically imposing bodies.
