To hunt the animals they follow
A better question might be, "What happened to all the earlier humans that left Africa?" Humans have been leaving Africa for 2 million years. Our branch left Kenya 60 thousand years ago. There were some Neanderthals left from an earlier migration out of Africa, but that was about it. Anyway, it took 10 thousand years to get to Australia. The food along that path was the same as it had been in Africa. Needless to say, life was dangerous and survival was difficult. In order for humans to move north, they had to solve several problems: How could they obtain food during periods when no food was available? How could they stay warm in colder weather? They had to create warmer clothing and discover a way to kill different animals. They created better stone tools so they could kill bigger animals, the middle stone age. They started wearing animal skins. At that point they became more successful than the Neanderthals. Then they could spread.
The staple food supply of the Shang dynasties was millet, but rice and wheat were also eaten. Animals bones that were discovered cause speculation that hunting was for leisure not for food.
Some challenges faced by early settlers in Australia were dense forests, clearing farmland by cutting trees, and finding food. The Aborigines were not very friendly to the newcomers either.

because the people in the Neolithic age learned how to desiccate animals and learn to make food for them self's

For food, tools and clothing.
Early humans depended on the herds of mammoths, bison, and other large animals for food, clothing, shelter, and many other things. So, when the big game moved, humans followed them.
They obtain there food by killing animals and gathering fruit and plants
they had a new source of food

Well, they needed food, so they follow the herds, and killed them, that was before they learned to cultivate the land for corps for food.
Early humans had to hunt or gather for food. You could only hunt where the animals were, so migrating animals forced humans to migrate to follow them. Also, you could only gather from the plants that are around you. If the weather gets cold or the plants die off, humans had to move to find more food. Farming allowed humans to grow enough food to live off of in one place. This was a more stable food source and led to the establishment of cities and communities because people didn't have to migrate anymore
Some early humans were nomadic because they did not know anything about agriculture and they had to follow the food (buffalo, deer, etc...) where ever it moved to.
The first humans lived in Africa about 3.6 million years ago. When these early humans were alive, the migrated to either follow migrating animals that they hunted for food, or they ran out resources on the old land and they lived on. From Africa they migrated to Europe, from Europe to Asia, Asia to North America, and from there to South America.
They moved because after a while they run out of food and resources. They also had to go ware the animals went.
Before people discovered how to farm, they had to follow the wild herds for food, and also when a plant food source was depleted, they needed to move on to find another.
