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

Today in Humanities we were assigned to write a blog post about "In the past, were did humans tend to settle and why?" Hear is why i think:

Early peoples tended to settle near water and open fields to grow their crops. They tended to settle near water because it provided them with water for there plants and for there family's. They tended to settle next to fields not only to grow crops but also to raise cattle and sheep and goats. I think that most of the people that migrated to these types of terrains are very smart but even tho back then they didn't have as much knowledge as we have today, they were still very intelligent. They also move/migrate because of climate change. For growing crops, they needed sunny and warm weather. If they were Eskimos, they would want to go to a much colder climates like Canada, the North pole and the South pole. If they migrated to a much hotter area, they wouldn't be able to use all of there tools and there sleds also because it would take them a long time to adapt to there new territory.

In the picture above, you can see the migration map from the early ages. Most of them, as you can see, are not off shore, because they didn't have boats that could travel that long. They mostly traveled by foot and when they did, not many people survived because of the ruff terrain.
