ELI5: Explain Like I'm 5

Darkness in El Dorado

Okay kiddo, let me explain to you what happened in the Darkness in El Dorado.
So a long time ago, some people called anthropologists went to a place called Yanomami in the Amazon forest. They went to learn more about the Yanomami people and how they lived. Sadly, these anthropologists didn't follow the right rules when they went there, and they did some really bad things that hurt the Yanomami people.
They gave them some shots that made them sick, and they even gave them weapons that made some Yanomami people fight with each other. This made the Yanomami people very upset and caused a lot of problems for them. It was like these anthropologists brought darkness to the Yanomami people and their way of life.
People found out about what happened later on, and they got really angry at the anthropologists for what they did. People now know that it's important to follow rules and respect different cultures when learning about them.
