I have been following - Fall of Civilizations - YouTube channel for years now. The host Paul Cooper writes, narriates, and produces these epic documentaries about lost civilizations. Calls it a Podcast. He releases a audio version, and then some months later releases the fully produced video. Not an easy task at 4 hours running time.
As he states in the intro of each episode: "I look at a civilization of the past that rose to glory and then collapsed into the ashes of history. I want to ask, what did they have in common? What led to their fall, and what did it feel like to be a person alive at the time who witnessed the end of their world?"
These rank up there with almost anything I have listened to or seen.
Including - Homemade Documentaries - by Jackson Tyler. Another YouYube documentarian, which I think I have posted here before - here is his latest work on Gemini, Crazy good at just under 3 hours.
