Who was the first person(s) alive, what was her/his name, what year were they born and pass away?
Question Date: 2016-05-25
Answer 1:

This is impossible to answer because we don't have a clear definition of what a "person" is. There are a number of extinct species of human-like animal, much more like us than like any other living thing today. However, they weren't the same as us. Were they other species of humans? Or were they human-like apes but not humans? This is a language question, not a science question.

The other parts of your question can't be answered either. If the first human didn't have language, then she/he did not have a name. If she/he did have language, then she/he probably did have a name, but we have no way of knowing what that name was (it probably wasn't "Adam").

The last common ancestor between humans and our closest living relative (chimpanzee) is about 5-7 million years ago. Therefore the first human must have been younger than that. The last common ancestor of all living humans is about 50 thousand years ago, so the first human must have been older than that. Besides those limits, it comes down to language.
