The African Humid Period is like when it rains a lot in a place where it usually doesn't rain that much. So, imagine if you lived in a very dry desert, where there is not a lot of water around. But, then one day it starts to rain a lot and you start to see puddles of water everywhere. This is what the African Humid Period is like for the continent of Africa.
Africa is a big continent with lots of different places, some of which are very dry and others that are very wet. But, a long time ago, around 10,000 years ago, there was a time when most of Africa became much wetter than it was before. This period lasted for a few thousand years and is called the African Humid Period.
During this time, many parts of Africa that were usually dry turned into green forests, where there were lots of trees, plants, and animals. This meant that people could start farming and growing their own food. They could also find more animals to hunt and fish to catch, which made it easier for them to survive.
The African Humid Period happened because of changes in the Earth's climate. The climate is like the weather, but it changes over a much longer period of time. So, during the African Humid Period, the Earth's climate changed and became much wetter in Africa than it was before. Scientists believe that this change might have been caused by changes in the Earth's orbit around the sun, or by changes in the amount of sunlight that the Earth received.
Once the African Humid Period ended, many parts of Africa became dry again. This made it more difficult for people to grow food and find enough water to survive. But, some parts of Africa still remain wet and lush today, and people have adapted to living in these areas by fishing, farming, and hunting for food.
