My view and impression upon this topic might be aligned with you. But for now we should keep this hypothetical assumption from entering the scientific realm. The majority of scientist are pushed away from talking about this subject. However the right appoach might be to surface more evidences and conduct more research. Australian researches had made a plead to conduct research and excavation around Seribu Islands, which is suspected to host many evidence leading into a more rigorously accepted theory but our government allegedly denied those request, thus the research halted. As for now all this we have to see as an inconclusive theory.
