They used levees, which were walls used to keep water flowing where it was wanted/ needed.
They needed leaders and they started to elect leaders to govern them but as time passed nobody did a good job governing and they decided to live lives as they pleased
It is important for a Supreme Court justice to be appointed for life because they make big decisions for the country and the longer they serve the more experience they will have. A presidential appointee in the supreme court can change a lot of the decisions made depending on their political alignment.
Hope this helped :)
