Homo sapiens have been on Earth for approximately 300,000 years, based on evidence from the fossil record.
So far it is believed that Homo Sapiens have been on Earth for approximately 200,000 to 250,000 years. However this estimation could change at any given time, should further evidence of Homo Sapiens being around earlier be found, which at the moment is looking unlikely.Although Homo Sapiens showed up around 200,000 - 250,000 years ago, civilisation as we know it has only been around for about 6,000 years. So Homo Sapiens were around a long time before they became the civilised variant that we know today. Industrialisation of civilisation only begun around 215 years ago (from 2015) in the 1800's.
Current estimates put the first appearance of homo sapiens in the fossil record between 160,000 and195,000 years ago. But, discoveries often change these estimates.
Some variance here but the spread on the emergence of modren humans, Homo sapiens, is from 200,000 to 100,000 years ago and in Africa.
Australopithecines appeared on Earth before Homo habilis, Neanderthals, and Homo sapiens.

Archaic H. sapiens appeared in the period beginning 500,000 years ago. They H. heidelbergensis, H. rhodesiensis, H. neanderthalensis and sometimes H.antecessor Anatomically modern humans appeared about 400,000 years ago.

According to the fossil records, the modern humans did appear on earth more than 130,000 years ago.
I don't know by fossil record but I have a book called walking with the dinosaurs and it said 220 million years ago
A fossil record is a historical sequence of life indicated by fossils found in layers of Earth's crust.
