The Mayans had mastered water pressure and had fountains and toilets as early as 750 AD.
Aztecs had running water and sewage.

The Victorians In the mid-1800s were dying of cholera because they just dumped their raw shit in the river Thames. They wouldn’t shower for months at a time because they were afraid of the polluted water.

Incans had created aquaducts in the slopes of the vast Andes mountains to reach the emperor, cities and farmers who used agricultural terraces.

Mayans, Aztecs, and Incans were far more advanced than the savage Europeans.

So were romans and Greeks. And prsia ans Egypt and the whole damn antique world!
The came the middle ages and it’s like humanity regressed.
Historians can explain how this came to be but frankly I will never understand.
How??

In some places famine caused a drastic reduction in population and a need to abandon the city in search of food. It can take several generations to stabilize the population in a new place and during that time the knowledge of how to build these things may have been lost. The people who knew how to do it were either wiped out early in the famine or too busy surviving to pass on their knowledge. Written instructions would get left behind when the survivors set off to find food

The superiority complex of nations can also be a cause. The ability to read hieroglyphs was lost for centuries because Egyptian priests were slaughtered by conquerors and they were the only ones living who knew how to read them. There’s a long history of the church ordering books be burned that they deemed heretical, but since conquerors often couldn’t read the books there’s no way to know what kind of knowledge was lost. Superiority complex also led to people not being willing to learn about these things from their neighbors, which meant the technology didn’t spread and would die out if a war or famine devastated the people.
