Since its first exploration by archaeologists in 1914 the site was thought to be a natural hill with 2500 year-old megalithic structures on top of it.But in 2010 geologist Dr Danny Hilman Natawidjaja (who earned his doctorate at Cal Tech) recognized this “hill” as a possible man-made pyramid and began to explore it using ground penetrating radar, seismic tomography, resistivity survey and other remote sensing techniques, as well as some direct excavations and deep core drilling.“Trying to understand what happened in human history to lead people to establish this sort of polity we felt was a gap in understanding that needed to be filled.”1 Before the mid-twentieth century, Egyptologists came up with dates for Egyptian unification ranging from 5500 BC to 2000 BC.
The following article by Graham Hancock refers to the basic evidence for the Gunung Padang site's age as well as the reaction from the orthodoxy of mainstream archeology.According to Hancock, mainstream archeology made an effort to prevent the exploration of the site using ground penetrating radar.The results were immediately intriguing (see this article I wrote in January for background: G9-Mystery-Lost-Civilization.php) producing evidence of deeply buried man-made chambers and yielding carbon dates going back as far as 26,000 years.This was the last Ice Age when our ancestors are supposed (according to the orthodox archaeological model) to be have been nothing more than primitive hunter gatherers incapable of large-scale construction and engineering feats.So, if this is indeed the case, then we do seem to be at a point in history where books will need to be thrown in the fire so that our actual history can be recorded more accurately to reflect what has been discovered both at this site, as well as sites such as The Pyramid of the Sun in Teotihuacan, Mexico (the Bosnian pyramid was given her name “pyramid of the sun” due to her similarities to Teotihuacan).
Once again, archaeological findings in recent times have given us food for thought as to how long we have actually been living on this planet. The last I heard it was only speculation that it was while a lot of people wrote the idea off as fantasy.
Another recent site discovery that completely disapproves this 6,000 year old timeline is that of Gobekli Tepe.

Researchers probing the ocean bottom have found 18-story-high towers of stone deep in the ocean near a section of volcanic fault ridges that extend for 6,200 miles along the Atlantic Ocean floor."9,000 B. - Jericho Settlement - "This city, located near a permanent spring a few miles west of the Jordan River was excavated by Kathleen Kenyon. Manfred Heun of the Agricultural University of Norway, along with Norwegian, German, and Italian colleagues, examined the DNA of 68 lines of cultivated einkorn (Triticum monococcum monococcum), 194 lines of wild einkorn (T. boeoticum) from nine geographical regions within the Fertile Crescent, and nine lines of a weedy einkorn (T. aegilopoides) found in the Balkans." - Fig Cultivation / Middle East - "[....] In the Middle East, figs were domesticated 11,400 years ago. In the New World, corn was being cultivated 9,000 years ago. Some scholars have proposed that the Sumerians came by ship, landing on the north shore of the Persian Gulf.' " 8,000 B. - Florida Indians - "Florida's Aucilla River is yielding evidence of the adaptability of Paleoindians to their changing environment at the end of the Pleistocene, 10,000 years ago.
There were indications of settlement after 9,000 B. For a decade, researchers from the Florida Museum of Natural History have been excavating the Page-Ladson site, and this past fall  they uncovered the ground surface of a Paleoindian habitation at a depth of 15 feet.
The version of history taught to us in school, that civilization has existed for only about 6,000 years, is now completely disproven.
