Because Ocean transport = acess to more food
How could early humans travel Africa to Australia without a boat?
from lakes, rivers, oceans the sea
To tell you the truth the first species of early humans to travel outside Africa are the Homo Erecuts.
the early humans traveled about 50,000 miles to get to America
Early humans used rivers for water to drink, cook, bathe, and irrigate crops; to fish; to swim; to travel; etc.
Lower sea levels during the ice ages created land bridges that connected continents, allowing early humans to migrate between them. The dropping sea levels also led to the formation of ice sheets, which lowered global temperatures and made these new land bridges more accessible to early humans.
because there was too many mountains to farm

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.
During the Ice Age, lower sea levels created land bridges between continents, like the Bering Land Bridge between Asia and North America. This allowed early humans to migrate to new continents in search of food and resources.
