Lemuria? Cripes...I have been out of high school now for 30 years and this fascination with "Lemuria" was a dead issue even back then. And, even when it was first imagined it was never considered to be a "mythical" land. At least the story of Atlantis has some historical foundation (i.e. Plato). But Lemuria has none whatsoever.
The concept of Lemuria originated in the 19th century, from attempts by scientists to account for discontinuities in biogeography. It was the result of scientists theorizing how certain geographies and fauna (namely the lemur; hence the name) could be explained in certain areas of Africa, Europe and Asia, and why some of it suddenly stopped in others...and that's it.
This concept of Lemuria has really been rendered obsolete since the modern understanding of plate tectonics (you know, that part of geography that we all learned in Grade-5). Although sunken continents do exist, nothing has ever been linked to anything called Lemuria, especially anything in the Indian Ocean.
This "Lemuria" story is nothing more than myth-building over the past 150 years, which is truly amazing when you consider how people now believe that Lemuria had an advanced civilization, with rocket ships, laser cannons, crystal weapons, a sophisticated political structure, a peaceful and Utopian society plus literature. I mean....come on people :-).
Something is not right. This message is just to keep things from messing up down the road
