I've been saying it for years, that there is no way that primitive humans carved some of these stones. If stone carving was so easy, especially today with the modern tools we have, then everyone would be doing it. I'd like to see someone carve a rock this size, to that precision with the tools that primitive humans had at the time. Even if they could shape the rock, how would they get it so precise? Even with modern tools, that is hard to achieve. There's something that has been hidden from us, as I believe many things have been found at these ancient sites and hidden.
S&F, BTW. Great thread. IT'S JUST A ROCK!!!!! lol

I agree with you completely OP. There are ancient sites all over this entire planet which are clearly not the works of primitive man.

I fail to believe that there were civilizations more advanced than us, simply because we haven't found ancient garbage-dumps/heaps that consist of more than pottery, bones, or crude metal objects. Supposing we do find anything noteworthy, it always seems to be more of an artisan work than something that was massed-produced for the general public (like pottery or etc.)
The question had been whether the early Amazon was highly deforested or barely touched, Carson said.
"The surprising thing we found was that it was neither," he told Live Science. "It was this third scenario where, when people first arrived on the landscape, the climate was drier."
The pollen in this time period came mostly from grasses and a few drought-resistant species of trees. After about 2,000 years ago, more and more tree pollen appears in the samples, including fewer drought-resistant species and more evergreens, the researchers report today (July 7) in the journal Proceedings of the National Academy of Sciences. Charcoal levels also went down, indicating a less-fire-prone landscape. These changes were largely driven by an increase in precipitation, Carson said.
The earthworks predate this shift, which reveals that the diggers of these ditches created them before the forest moved in around them. They continued to live in the area as it became forested, probably keeping clear regions around their structures, Carson said.
"It kind of makes sense," he said. "It's easier to stomp on a sapling than it is to cut down a big Amazonian tree with a stone ax."
