| I should add that Kirill Yeskov is a paleontologist and science popularizer. Here's his own explanation how he wrote "The Last Ringbearer": one of the reasons he mentions is that Middle Earth was impossible geologically: https://fan-lib-ru.translate.goog/e/eskov/text_0150.shtml?_x... In which he also mentions another famous book: "It would hardly occur to anyone to seriously analyze the functioning of the ecosystem of a barren desert inhabited by predatory worms the size of a multiple unit train that feed on walking excavators and then sweat psychedelics: fantasy is fantasy, what do you want from it?" He also wrote a great book on the Earth evolution and life evolution, in which he also explains how science works and worked earlier, and what were older theories, and Popper criterium as well. Here are some of his lectures for example: https://www.youtube.com/watch?v=eEp7o0-w-uU ..and an interview with some charts

Unfortunately he missed the answer: at the time Tolkien was writing, plate tectonics was still considered an absurd hypothesis, the subject of mockery by "serious" geologists. As such the understanding of "geologically impossible" at that time was rather different than when Yeskov was writing a few decades later.
It was not until the 1950s that widespread sea floor mapping and research, made possible by the now-unnecessarily-large-and-mostly-idle US Navy, provided conclusive evidence that forced the geology establishment to accept plate tectonics.
It's easy to forget how recently we stopped being totally wrong about things like that.
