Godzilla 2: Why can't humans defeat Godzilla?

Godzilla is the most powerful creature on earth. They are ancient predators who lived millions of years ago. Revealing these titans in the movie may be one of the defense mechanisms of the earth itself, or the planet should be their home. Humans are as small as ants in front of Titan, so they can only choose to be attached to the protection of giants. In fact, there are two ways to defeat Godzilla in movies, one of which is the oxygen destroyer. The second way is that only monsters are monsters' opponents. In order to fight against Godzilla, human beings need to create more terrible monsters, but this is almost impossible.
