Why did Sumer become the place of the first cities?

homework?

I believe the correct answer is “C”- The once fertile valley of the Tigress and Euphrates River is the cradle of civilization. oh wait, that’s Iraq

I’m not sure this is the correct assumption. There is evidence that other, earlier cities existed long before Sumer.

Cities arose with intellectual, forward thinking people. Mass migrations weren’t particularly common once we left the nomadic era, so where the people with the abilities to rule a kingdom sprang up, which then built cities to house its people and display its strength.

@PandoraBoxx lol it is the correct answer though, Sumeria was in more or less the same area.

What we now call the Middle East was not as hot or as dry in those days. There were two main rivers, fertile land and even ore resources. That mean there was not just plenty of food (with the possibility to breed a variety of useful animals such as cattle or sheep) but also the materials to make things (mainly bronze and iron). And of course the spaceships from other galaxies with all the little green men who offered cheap labour. All of this helped in the birth of a relatively huge population, which could live in health and prosperity with few external enemies or internal strife, and therefore prosper and create a healthy and wealthy civilisation.

1.) number of domesticated animal species
2.) number of domesticated crops
3.) established water supply
4.) fundamental resources (ore, wood)

in a nutshell.
