In the past, where did humans tend to settle and why?

Humans settled in places around the world, they chose there place according to their need and wants. Of course there needs would be their shelter,food and water. They need to find a region that is going to suit there food and shelter need, so humans would settle close to lakes,rivers for water but not too close in some regions because of mosquito's carrying Malaria and other diseases. There region must have some kind of habitat for them to make a shelter (eg. Egyptians close to the Nile would use mud from that river to make there huts or wood supplies).The region must also have a specific food source for them to live off, (eg. Close to fresh water river would maybe have salmon or they could farm if the place they settled is flat or they could be close to trading lines).Lastly they need water(eg.Rivers, Lakes or filtration of water that is not drinkable also trading would work.)

So as you can see our ancestors needed A reliable food source,water and shelter, these factors made the humans settle in places

Shelter made out of materials from habitat
