Location.
Anyone who inspects a chart of the oceanic bottoms in the region of Indonesia such as the Ice Age Map of Indonesia shown in Image 1 , will readily concede that the South China Sea encircled by Indonesia indeed formed a continent during the last glaciation, which ended some 11,600 years ago. This chart clearly shows the sunken continent of Lemurian Atlantis in Indonesia, as well as the extensive sunken strip of Indian Atlantis at the Indus Delta.
The map leaves no room for doubt about the reality of what we are affirming concerning Lemurian and Indian Atlantis, one almost wholly sunken, and the other sunken to a very considerable extension. It is based on the detailed geophysical reconstruction of the seabottoms in the region in question, and portrays the areas of depth under 100 meters, which were obviously exposed during the Ice Age, when sea level dropped by that amount and even more.
As the map above show, a huge extension of continental size prolonged Southeast Asia all the way down to Australia. This continental-sized land was indeed "larger than Asia Minor and Lybia put together", exactly as Plato affirms. It is seen to have been about two or three times larger than continental-sized India.
The Indonesian Islands and the Malay Peninsula that we nowadays observe are the unsunken relicts of Lemurian Atlantis, the lofty volcanic mountains that became the volcanic islands of this region, the true site of Paradise in all ancient traditions. The sunken portion of continental extension now forms the muddy, shallow bottoms of the South China Sea. It is encircled by Indonesia and forms the boundary of the Indian and the Pacific Oceans.
Then, as now, Indonesia formed the divide of the New and the Ancient Worlds; what the ancients called Ultima Thule (Ultimate Divide). Thule also corresponded to what our elders named the Pillars of Hercules, which, according to Plato, were placed "just in front of Atlantis"
The Pillars of Hercules were also the impassable frontier between the Old and the New Worlds, also called Orient and Occident. These two are sundered by the volcanic island arc of Indonesia, truly the boundary of the Tectonic Plates that form the Ancient and the New Worlds. This barrier to navigation, in the region of Atlantis is also insistently mentioned in Plato and other ancient sources on Atlantis.
