Your English is quite poor. I assume you are asking how long have humans inhabited the earth and been in existence.
An early form of human (but not anatomically) began 500,000 years ago. Anatomically modern humans appeared about 200,000 years ago.
Non-modern varieties of Homo are certain to have survived until after 30,000 years ago, and perhaps until as recent as 10,000 years ago.
