Quick Answer
According to the provided evidence, ordinary humans cannot defeat Superman because he is an archetypal superhero with extraordinary abilities that fundamentally set him apart from normal humans.
Explanation
The verified evidence establishes that Superman is a superhero with extraordinary abilities, wearing an outlandish costume and using a codename to fight evil and avert disasters. The definitions and conventions of superheroes, as established by Superman, inherently involve powers far beyond those of ordinary humans.
