Science in the twenty-first century does not encourage scientists to take risks in their pursuit of "the facts"—particularly when those facts call in… - Graham Hancock

[At Gunung Padang] First, the drill cores contained evidence — fragments of worked columnar basalt — that more man-made megalithic structures lay far beneath the surface. Secondly, the organic materials brought up in the drill cores began to yield older and older dates — 3000 BC to 5000 BC, then 9600 BC as the drills bit deeper, then around 11,000 BC, then 15,000 BC and finally, at depths of 27.5 meters (90 feet) and more, an astonishing sequence of dates of 20,000 BC to 22,000 BC and earlier. [...] The problem is that those dates going back before 9600 BC take us deep into the last Ice Age, when Indonesia was not a series of islands as it is today but was part of a vast antediluvian Southeast Asian continent dubbed "Sundaland" by geologists. Sea level was 122 meters (400 feet) lower then. Huge ice caps 3.2 kilometers (2 miles) deep covered most of Europe and North America until the ice caps began to melt. Then all the water stored in them returned to the oceans and sea-level rose, submerging many parts of the world where humans had previously lived.

Across the ages and regardless of geography, in everything that really matters, it bears repeating that we are all members of a SINGLE human family — a family of intrepid adventurers who have been exploring the world in one form or another for the best part of a million years.18 In the course of this long odyssey we've moved so far apart, across oceans, over mountains, and to the opposite ends of jungles, deserts, and ice caps that we've forgotten how closely related we in fact are. In this sense, like the simple human message of the burials, the message of genetics also speaks to a hidden unity within our apparent diversity — and sometimes in ways that defy our expectations.

The earth is a dynamic place [...] with multiple different processes of deposition and erosion under way at all times. You can make guesses based on style and weathering, but fragments of worked stone that have been in the open for an unknown period can't be dated by their archaeological context, because there is none. Carbon-dating organic materials in the sediment in which they were found won't work, either, because they were never entombed and preserved in sediment. And in fact no other objective and widely accepted method of dating can tell us how old they are. For these reasons archaeologists have to discount artifacts found on the surface when coming to any conclusions about the age of a site, even though the artifacts themselves may obviously be ancient.
