Once upon a time, there was a landmass shaped like a crocodile foot. Its name was Sundaland and it dwarfed the neighbouring Indian subcontinent. Here, in the birthplace of the Neolithic Revolution 10,000 years ago, rice was first grown, bronze first smelted. So why haven’t you heard of it? The sea swallowed up most of it about 14,000 years ago. Until 1998, Stephen Oppenheimer, suggests that the drowned continent of the Atlantis is probably in Southeast Asia; the South China Sea, the Gulf of Bangkok and the Java Sea were all dry plains connecting Indo-China, Borneo, Sumatra and Java into, one continent.
