Why did people in ancient times not have large civilizations on the Mississippi River like they did on the ?

Nile and Mesopotamia. Also why were Native Americans in the U.S. not as advanced as there brothers to the south like the inca, maya, and aztec. From what I read the natural resources and farming land around the Mississippi River were comparable to that of the Nile during ancient times and Mesopotamia. So why were there not any ancient civilations that made as big as an impact as Sumer and ancient Egypt?
