The South Pacific, I believe, was the site of the first sea-bound "Originators" (Giants). They spread from Asia into Europe and the Middle East, but they also took to the water and spread out even further. Some of their first occupations outside of Asia, Europe and Africa would have been the South Pacific, on to South America and upward to their latter civilizations in North America.
As I see it, Homo erectus and its offshoots - Heidelbergensis and Neanderthal, perhaps Denisovan, were building tools and creating civilized means within the continent of Africa. Even researchers admit Homo Sapiens when they came along, were utilizing the tools left by them when they exited Africa long before. Even in Homo sapiens infancy, he was beginning to utilize the technology left behind without earning the original learning experience that Heidelbergensis had to go through. When the Homo Erectus offshoots took to the lands outside of Africa, they already had tools and their adaptation to new lands allowed them to have many hundreds of thousands of years ahead of homo sapiens, learning much, including canal building, metallurgy and seafaring. When Homo sapiens stumbled out of Africa 80,000 years ago, there were already civilizations around the world.
That is my theory.
Do we have proof that these "Originators" settled the South Pacific first? Well, even the natives tell us this -
Examples are everywhere in legends and in ancient art. Let's take for example the legend of the TaoTaoMona - or "people before history" or "ancient people." They believe the spirits of these ancient inhabitants still haunt their mountains and wild areas from Mariana Islands to Guam and Micronesia. People today, still carry the tales and the belief of the TaoTaoMona.
Source: Guam's indigenous Chamorus believe that the twilight before sunrise and the twilight at sunset are the periods when the spirits begin to stir and move through the land at night. The taotaomona commonly assumes the form of a male physically large and robust. Other metaphysical forms taken may be white lady aparitions accompanied by scents of flowers or lemon, large men or 'small children called duendes hiding under mushrooms'. Some of the taotaomonas are described as headless and having deformed bodies. The Spanish era traditional depiction is that they were giants but monstrously ugly. This ancient concept of ghost is incongruous "to Christian beliefs and referred to as pagan ghostly forest-men" [pg 89, The Chamorro]. The modern contemporary view however is that the taotaomona are living ancestral spirits. Mavis Warner Van Peenan, "Chamorro Legends on the Island of Guam 1945" wrote, "Could that ugliness be the self-deprecation that the Chamorro felt was required of him under conquest?"
These stone pillars (above) in Guam are ancient construction. They appear to be pillars with a bowl shaped stone with flat top that looks ideal for placing a roof. Rather tall stone pillars for a high roof (look at the size of the people in comparison) for small island people, hmm? The work of the TaoTaoMona when they lived there? This is the most likely conclusion. It is also interesting when you compare it to this other famous South Pacific site -
These may not be hats at all on the Easter Island Moai statues, but stones meant to hold up a roof to. If you compare the carving of the TaoTaoMona from Guam (top of the post) and their pillars with "hats" on top - you find similar features in both! The RapaNui had legends of the "long-earreds" that built the statues and the wars between them and there was clear-cut evidence of cannibalism on the island (another feature of the "originators" who were carnivorous and hence found waterways great sources of constant meat unlike chasing down creatures in the forest and thus built along waterways). Here is my post on the Easter Island "Originators."
Called the "Venice of the Pacific," Nan Madol in Micronesia is the ruins of an ancient city that included a canal system! Little can be verified about the megalithic construction. Pohnpeian tradition claims that the builders of the Lelu complex on Kosrae(likewise composed of huge stone buildings) migrated to Pohnpei, where they used their skills and experience to build the even more impressive Nan Madol complex. According to Pohnpeian legend, Nan Madol was constructed by twin sorcerers Olisihpa and Olosohpa from the mythical Western Katau, or Kanamwayso. The brothers arrived in a large canoe seeking a place to build an altar so that they could worship Nahnisohn Sahpw, the god of agriculture. After several false starts, the two brothers successfully built an altar off Temwen Island, where they performed their rituals. In legend, these brothers levitated the huge stones with the aid of a flying dragon (There's that symbol again!)
Source: "I would also like to draw your attention to the fact that there are many remains of a lost civilisation of the giant race scattered in different parts of Malaita. I say “civilisation” for a very good reason. Around a mountain near Mt. Mala in North Malaita’s interior, is a perfectly fitting large stone block wall spiralling around the mountain. This path leads to a flat area on the top of the mountain where another large stone block wall separates off a higher, split-level flat area where a stone altar can be found. Further on is a burial site which has a perfectly flat 18ft x 6ft x 1ft stone slab upon it. The bush people who live further away from that area say that a Ramo of great importance is buried there. [...]
Who can - or could - those enigmatic Ramo be? We are dealing here with as many as three different interpretations. According to the words of Boirayon himself, included in the articles that can be found on the Internet, the name should be associated with the legendary hairy tall hominoids that exist between myth and reality - with Giants. According to some other sources, Ramo (or lamo) is a warrior-chief among some of Malaita's tribes. He became such after he has killed an enemy in a direct encounter, thus winning fame and obedience. He also led his clan to fight in a bloody revenge for breaking holy laws and prohibitions by an outsider.
As far as I am concerned, the word Ramo and the whole Boirayon's description bring to mind a hypothesis put forward by a Polish author Igor Witkowski in his book "Axis of the World" (available also in English), namely that tens of thousands of years ago representatives of the highly advanced Indus Valley civilisation began their journey eastwards towards South America (modern Bolivia), stopping on their way at Pacific islands and leaving behind megalithic structures.
Therefore, provided that Boirayon's sensations would indeed find their confirmation in reality, they could refer to a structure and tomb/grave built by descendants of the inhabitants of Harappa and Mohenjo Daro rather than by gigantic, hairy and "talking" "anthropoids"!!!
Do they really exist in the place indicated by Boirayon (8 degrees, 41 minutes and 06.88 seconds South, 160 degrees, 45 minutes and 43.42 seconds East)?"
Manisan Mountain in South Korea is an interesting site. Source: Chamseongdan is a large stone altar that was originally built in the 24th century BCE. According to legend, the founder of Korea, Dangun, built it himself, and made sacrifices here to the heavens.
Source: Tongatapu island in Tonga has this interesting (above) megalith that has stones of 50 tons! Tonga also has a plethora of stepped-ceremonial platforms and megalithic ruins. One of these ruins is a megalithic archway only comparable to Stonehenge and the Osirion of Egypt.
The megalithic temples of Malta were built between 3000 BC and 700 BC. Source: Maltese folklore describes giants as having built the temples, which led to the name Ġgantija, meaning 'Giants’ tower'
Source: Maori oral tradition tells us how the art of facial tattooing and design was learned from the former inhabitants called the Patu-paiarehe, who fitted the description of Europeans. Recent finds of Caucasian mummified remains in China, with "moko-like" designs painted onto the faces, show us that early era Indo-Europeans adorned the faces of their dead with the "double spiral".
The double spiral was seen around the world - a "universal" symbol.
Source: Kaimanawa Wall has caused much conflict. The Maori people do not want to accept an earlier culture and archaeologists have helped that end by reporting they think this wall occurred naturally. A convincing explanation supported by evidence-based proof on either side of the argument has yet to be seen, but the controversy surrounding the Kaimanawa wall does raise important questions about how willing people really are to investigate the true origins of man and its early civilizations.
There is such a lot more in terms of megaliths and legends of the South Pacific settlements that all that alone would fill a huge book. This is only a sampling of the common links between legend and physical proof (those "kernels" of truth). Here's more sources below (along with links provided above) for you to peruse the mysteries yourself.
