And there is an underwater sunken civilization like Atlantis, called Lemuria.

Got anything credible to back that assertion up?

There are sunken and semi-sunken cities among the islands around Japan and the South Seas. Somebody was doing something architectural and civilized in areas that are below water now. What it was called then who knows, but there are stone ruins even 300 feet down. We have only begun to identify and explore these. I'm sure we can find a few cites on the Internet if you wish to begin researching this.
