That's why I don't have much care about Lemuria. Though, some writers make it parallel to Atlantis. But, I cited the following phrase from Wikipedia:
... the concept of Lemuria has been rendered obsolete by modern theories of plate tectonics. Although sunken continents do exist – like Zealandia in the Pacific as well as Mauritia and the Kerguelen Plateau in the Indian Ocean – there is no known geological formation under the Indian or Pacific Oceans that corresponds to the hypothetical Lemuria.
