I watched that video. Takes forever because you have to read each page. Would be very helpful if producer of video could just post the book. Seems like reasonable and researched info except the nonsense when he claims the world is not a globe. Ugh. Why do so many feel the need to drop in some ridiculous theory in otherwise decent info? Is it a form of plausible deniability if they have to deny the info? Oh, I am just a crazy conspiracy theorist. See my bit about the flat earth.
Also, seeing Zoro Astrianism and East Persia pop up more recently. Noticed in movie Bohemian Rhapsody that twice they make a point of saying that Freddie Mercury was Zoro-Astrian, not Farsi. No coincidences.
