The reason for the existence of classes is that people are reluctant to face their own insignificance and nothingness. Essentially, we are no different from other Earth citizens. All are guests and parasites of the Earth, enjoying its resources and trying to live a better life. Animals just don't speak human language. They have their own language. We don't speak tigers or birds either, because that doesn't conform to our communication habits. It's not that one is more advanced than the other; it's just that the systems are different. But humans soon discovered the convenience of mobilizing resources and were very eager to be different. So to describe oneself in terms of evolution, this expression of evolution transcends the classes and genera of the Earth and crosses species... Then that's not enough. They also need to stand out among their own kind. How can they make themselves stand out? Plundering and resources, essentially, are about not being willing to face their own mediocrity. Humans are all the same, there's no difference
