Sure, but that’s not what they are asking. A scream, a shout and a metal growl are different things, they asked about screaming.

You have to stop projecting the sound from the diaphragm and move it to the throat. Essentially the opposite from singing instructions. It is obviously really bad for the vocal cords.

There are records of population dying from diseases, but the magnitude was known only recently. And the records they destroyed were mainly Aztec and Inca, which are known as large civilizations, as opposed to the amazonian ones. It’s now that they were nice, it’s that there was no knowledge that there was anything to search. Only the quest for El Dorado counts and has been regarded for the longest time as looking for a fairy tale.

Come on! There is a reason why the fights against the Aztecs and Incas is called a conquest and none in the rest of the Americas is called like that and it is precisely because there wasn’t enough of a civilization to make an organized war instead of being just massacred, enslaved or subdued.

It is very normal to assume that if you don’t find anything suggesting a large civilization, there isn’t any. We are just discovering that we didn’t find anything because it was covered over by nature. Nothing different than what happened with North American cities that have also been found in a similar way or with a lot of the Mesoamerican pyramids or even in Egypt 200 years ago.

If you have no understanding of germ theory or how you could indirectly lead to the death of 90% of the population before you even set foot in a place and by the time you do, nature has swallowed everything and the few remaining survivors don’t have written records of the history, it’s not going to be the normal assumption that there used to be a large civilization in there, especially since some other places did have a more tribal civilization, so it wasn’t something strange.

This time it is more about lack of knowledge than European hubris, in my opinion.
