Debunking David Hatcher-Childress' new book on ancient megaliths in South America -- I have a response from a professor in archaeology, Dennis Ogburn, who specializes in South American archaeology in Peru and Ecuador:
The stones were shaped by hand, primarily using harder rounded stones (often quartz river cobbles), and I've seen a number of these in the stone quarries. They also used some bronze tools to extract blocks, but the shaping involving battering the blocks with the hammerstones. Moving the largest stones involved dragging them with ropes, and often required a thousand men or more. They only moved the largest stones over short distances of a few kilometers. The stones they moved up to Ecuador were still quite large, but only up to about 700 kg/1,500 lbs - these I suspect were carried on something made from wooden poles, like a litter. Archaeologists and other researchers have done quite a bit of work on these questions, and there is plenty of historical and archaeological evidence to show that the Incas were quite capable of doing these things using very basic technology in combination with the labor of many thousands of their subjects.
The Incas used simple, labor-intensive technology to help carve and move the stones harvested from nearby rockfalls. Many weighed more than 100 metric tons. Stonemasons shaped the blocks using a simple, effective method called flaking and a neolithic tool called a hammer stone. Made of granite, quartzite, or olivine basalt, hammer stones have a hardness of at least 5.5 on the Mohs scale, about the same hardness as the larger stones. Striking at a 15- to 20-degree angle, stonemasons could chip off pieces of the rock; alterations in the angle and force of the blow determined the size of the chips. Twenty quarry workers took about two weeks to dress four sides of one stone measuring 4.5 by 3.2 by 1.7 meters (14.8 by 10.5 by 5.6 feet).

You mentioned the Baalbek stone and the large obelisk which were never moved, nor the 26,000 ton one in China - probably just to difficult or they ran out of resources to do so. There is a limit imposed by rope technology.
The team members think the individual descended from an earlier species that may have spread out of the region hundreds of thousands of years ago and given rise to Neanderthals in Europe and their equivalents in Asia. The scientists have named the newly discovered lineage the "Nesher Ramla Homo type"
Scientists believe the girl had a local ancestry that had been present in Sulawesi from the arrival of modern humans up to 30,000 years earlier. The mysterious population may be responsible for ancient cave art in the area as well. They belonged to a group of hunter-gatherers called the Toalean, who killed prey with stone-tipped arrowheads known as Maros points.

I think this thread was before my time, but I have to mention a fairly straightforward prediction you could make if Neanderthal were to breed with Sapien.
Sapiens has small eyes. Neanderthal has big eyes. Neanderthal would probably also have a larger visual cortex, to control and make use of those larger eyes. '
What happens if the offspring inherits the Neanderthal's bigger visual cortex, but ends up with the Sapiens smaller eyes?
One could predict that their visual cortex would have excess processing power. More than it needs. What do we call it when a person uses their visual cortex for something other than controlling their eyes? I think the word is "imagination".
