I just watched a few of these videos. https://rumble.com/c/c-5649851/videos Right away they seemed like some kind of debunker-food trap to discredit revisionist historians.

Old World is Worldwide? | Part 5 https://rumble.com/v2jn22a-old-world-is-worldwide-part-5.html The narrator says that the Palace of Fine Arts in San Francisco* probably wasn't built when we are told it was and that it was too difficult to build in that short amount of time so it's probably much older. With just a little research the scenario described in the video can be shown to be bogus.

All the videos in that channel page were probably a big project thought up by some public-relations agency hired by the government. I only watched a few of them so there might be a few truths mixed in but the above video shows an intent to deceive. * https://www.kqed.org/arts/11079113/three-plans-what-the-future-holds-for-the-palace-of-fine-arts
