Why cant people be called animals but people?

It's a matter of classification and perspective:

* Scientifically, humans ARE animals. We belong to the animal kingdom, specifically the class Mammalia. We share common ancestors with other animals, and our bodies function similarly.

* Linguistically, "animal" often carries a connotation. We tend to use "animal" to refer to non-human creatures, especially those considered less intelligent or capable than humans. This usage can be dismissive or even dehumanizing.

* Emphasizing our shared humanity. Calling people "animals" can downplay our unique abilities and responsibilities as a species. We have language, complex thought, and a deep capacity for empathy and morality – these things set us apart from other animals, even if we share biological roots.

In summary:

* It's scientifically accurate to call humans animals.

* The term "animal" often carries negative connotations.

* Using "people" emphasizes our shared humanity and unique abilities.

The best way to refer to humans is to use terms like "people," "humans," or "human beings." This avoids potential misunderstandings and emphasizes our shared humanity.
