Maybe not, but it's nevertheless the most common name given to the very concept of a lost civilisation next to "Mu", "Lemuria", "Hyperborea", "Eden" or "Thule". Although there are indications that's at least one unknown advanced society did exist in our very deep past, we don't have nearly enough information to know if these names refer to several real civilisation, one civilisation or if they were made-up. All we have are just bits and pieces of anarchronistic technology and confusing myths passed orally from generation to generation before they were ever written down.
