Human evolution was a gradual process over millions of years. There was no specific point where one individual became the first human. Instead, there were populations of hominids that gradually evolved, with new traits emerging over time.

It's like asking who the first person to be "tall" was. Height is a spectrum, and there wasn't a specific point where someone became the first tall person.

So, there's no way to pinpoint a single individual as the first person on Earth.
