Time travel had a big effect.
Early humans likely reached the continent of South America last, as evidence suggests they migrated there around 15,000-20,000 years ago. This migration is believed to have occurred via the Bering Land Bridge which connected Siberia to Alaska during the last Ice Age.
Approximately 40,000 years ago, humans reached the continent of Australia. They are believed to have arrived there via watercraft from Asia.
Africa.
Early humans first appeared in Africa. The oldest known fossils of early human ancestors, such as Ardipithecus and Australopithecus, have been found in East Africa, indicating that Africa is the continent where early humans originated.
Most scientists believe that humans originated in Africa.
To go from one continent to another, humans had to travel by foot or by horse. Unless, of course, there was water in between. The invention of ships made it possible to go between continents.

Early humans were able to travel from one continent to another by using land bridges that connected continents during periods of lower sea levels, such as the Bering Land Bridge that allowed migration from Asia to North America. They may have also used primitive watercraft to cross short stretches of water.
Humans travel to and from the Antarctic continent when it is accessible either by ship or by airplane. During the winter season -- when the sun isn't shining, the continent is not accessible.

Antarctica is considered the last continent to be discovered by humans. The first confirmed sighting of the continent occurred in 1820.
During the Ice Age, lower sea levels exposed land bridges connecting continents such as the Bering Land Bridge between North America and Asia. This allowed humans and other animals to migrate across continents.
Some of them are not all of them are caused by humans
Humans do not inhabit the continent of Antarctica permanently, but there are settlements there where teams of scientists study aspects of the great frozen continent.
You'd be required to walk on water to another continent, where you could find shops.
Feet and/or boats. Land bridges created by lowered sea levels during the last period of glaciation also helped mobility between continents.
