Excavation on the Gobekli Tepe site only began in the year 2000 and the structure has been carbon-dated to 10,000 BC. That's almost 5,000 years older than the cities and artifacts of Sumeria, long propounded to be the oldest civilization in history. If these findings weren't astonishing enough, there is also indisputable evidence that this whole ancient site was deliberately buried and hidden from view in 8,000 BC. Linda Moulton Howe's assessment of Gobekli Tepe is unsurprisingly out of this world. She claims that a deep inspection of the ruins reveal an ancient alien technology.
