The incredible human journey is like a big adventure to discover where our human ancestors came from and how they spread out all over the world!
Long, long time ago, there were no people living on earth. But then, scientists say that our very first human ancestors were born in Africa. They were just like monkeys, but with a bigger brain and better control over their bodies. They learned to make tools and hunt for their food.
For a really long time, these humans lived only in Africa. But as time went by, some of them started to move out and explore new places. They walked and walked and walked until they reached new lands. This was really hard, because they had to cross big rivers, climb mountains, and deal with different climates.
But they did it! And as they went to new places, they adapted to them. For example, some humans who lived in cold places grew taller and stronger to deal with the cold weather. Other humans who lived near water became good at swimming and fishing.
And so, humans spread out all over the world, from Africa to Asia and Europe, and even to the Americas! As they moved, they changed in many ways, to become the different cultures and people that we have today.
So, that's the incredible human journey – a story of adventure, survival, and adaptation!
