Here's why:

* Biological Classification: Humans are classified scientifically as *Homo sapiens*. This name refers to the species, not individual people.

* Individual Identity: Scientific names are used to identify and classify organisms, not individuals.

* Personal Names: In everyday life, we use personal names to identify individuals. These names are cultural and social constructs.

In summary: While we have a scientific name for the human species, there's no single scientific name used to identify individual people.
