Origins of Post-deluge civilizations
Conjecture of origins of post-deluge civilizations
1. Civilization – As written by many authors, humanity was first flourished in Sundaland where ideal climatic conditions for development were found, and it was there that they invented farming, agriculture, trading and civilization.
2. Language – Scholastic belief by etymologists and linguists are positive that all world languages sprang from a common source. Paleo-Sanskrit is one of the theories that it is the ancestor of Sanskrit, Indo-Iranian, Indo-European, Mesoamerican, Sino-Tibetan, Austronesian and all other languages of the world.
3. Myths and doctrines – All the gods and goddesses of various world religions are parallel. Similar myths of great floods, creation and heaven are found all over the world. Brahma, Abram, Avram, Abraham and Ibrahim are believed by some as the same person.
4. Pyramid building – There are hundreds of pyramids still standing all over the world. Cultures separated by oceans, who supposedly never discovered each other’s existence, built these giant triangular structures, aligned them to cardinal directions, encoded within them sacred geometry/math, and used them as sepultures. The Gunung Padang pyramid in West Java, Indonesia dated 23,000 BC or earlier is claimed to be the earliest one.
5. Boat and ship building – Boat and ship have been the instrumental in the development of civilization, affording humanity greater mobility than travel over land, whether for trade, transport or warfare, and the capacity for fishing. Similarities among boat and ship building technology in the Austronesian and other parts of the world were observed. The earliest seaworthy boats may have been developed as early as 40,000 years ago, according to one hypothesis explaining the habitation of Melanesia and Australia.
6. And so on.
