Between 100,000 and 200,000 years ago on the African continent.
Homo sapiens
According to the most recent NY Earth Science reference tables, the earliest epoch that humans existed was the Pleistocene epoch. The following epoch is the Holocene epoch, the one we currently live in.

Since the natural selection is a theory, we can not apply a theory as a science. Even though some scientists believed in natural selection: think of Nazi scientists, Soviet scientists, etc. They were 100% evolutionist believers. Nobody yet seen atoms but we believe that they exist...strange. We apply faith in some modern science...hmmm...
Although there is no fossil evidence for the evolution of eukaryotes from prokaryotes, scientists have inferred this through studying modern organisms. Scientists believe that eukaryotes evolved from prokaryotes because both have RNA and DNA as genetic material, contain ribosomes, and also utilize the identical 20 amino acids.

Scientists believe early modern humans originated in Africa. This theory is supported by fossil and genetic evidence that suggests humans evolved in Africa before migrating to other continents.

If you mean where did human originate, scientists believe modern humans evolved in Africa and migrated elsewhere.
Asian populations have been present on Earth for tens of thousands of years, with ancient human remains found in Asia dating back to over 50,000 years. The specific time frame for the appearance of Asians on Earth corresponds with the migration patterns of early humans out of Africa and into Asia.
Cro-Magnon likely communicated through a combination of verbal language, gestures, and possibly some form of primitive written communication. They may have used sounds, facial expressions, body language, and symbols to convey meaning and share information with each other.
Homo sapiens
Modern humans (homo sapiens) last appeared in Brazil.
Scientists classify men under the genus Homo, along with other species like Homo sapiens, Homo neanderthalensis, and Homo erectus.
