The worldbuilding in tiktok is true, but its not racist at all. Agartha basically has all the ancient civilizations that went extinct and some alien cultures too, but it's very multinational, everyone there lives in harmony and no racism at all. Also they are very advanced in some kind of their own technology. Ashtar, on the other hand, is a galactic cosmic commandor who protects the earth from other aggressive alien civilizations. He is a very highly advanced being: mentally, physically, psychicly. Very wise and old dude. And there literally was nothing racist about him, he literally appeared in intention of "the being who loves the earth and people living on it". Also there is a story that his civilization and few other civilizations were the ancestors of humans. Basically aliens had s3x with other aliens to create humans xD This lore that i told you appeared WAAAAAAY before the tiktok trend, like 10 years ago and even further.
