Mesopotamia Similarities

Some countries of the world are/used to be really similar to each other; however, since everything at least has one difference, so do these two regions that I’m going to be talking about (Egypt and Mesopotamia). They are very alike in many ways even though they were around in different times, about 300 years apart. I will first tell you about the similarities of these two regions.
A similarity of the two countries is that they both have rivers that contribute to well-being of the land and the people that settle near the water. Along with this similarity, it is that the rivers both flood and dry out according to the time of year. Another piece of information that is alike about the two is that they both have labels for the upper and lower parts
