Extraterrestrial Civilizations And Why We Can't Detect Them

In this video, I take a look at the reasons as to why extraterrestrial civilizations currently exist or will eventually exist and then go over the reasons as to why we can’t detect traces of extraterrestrial civilizations that currently exist or the traces of ones that existed and went extinct.
(I also try to calculate as to what approximately the number of planets in the observable universe is and connect it to the idea of extraterrestrial civilizations existing)

The majority of the footage in this video was made with Space Engine.
