How long have people been alive?

Answer 1

A long time that's for sure.

Answer:

If you only include members of genus homo going back through the archaic types (Homo heidelbergensis, Homo rhodesiensis, Homo neanderthalensis ) then you are looking at a period beginning 500,000 years into the past. Including hominid ancestors would put the earliest types back to 4 million yeas before the present. Only including "anatomically modern" humans limits you to about 200,000 years ago. Further limiting yourself to socially and culturally modern humans decreases the history to 50,000 years before the present.

Answer 2

The existence of anatomically modern humans dates back to around 200,000 years ago, based on fossil and genetic evidence. However, the history of life on Earth spans billions of years, from the first single-celled organisms to the diverse life forms present today.

Answer 3

People (homo sapiens) have been alive for something on the order of 200,000 years.
