Scott,
There are links to investigation of the stones in the wiki article that suggest they are fakes.
Some of these stones seem to depict advanced technology, such as flying machines. Also, the pictures are not accurate: fingers/toes on the limbs, Tyrannosaurus is in a standing up position as it was believed at the time.
Also, there are some people who believe extraterrestrials created the stones.

I agree that the dinosaurs are standing in the wrong positions, but if your going to carve them on stone, or make statues you have to make them in the Old positions. Simply because on the stone the tail would wrap almost all the way around the stone, and the sculptures wouldn't balance either. Same goes for the feet, but there were also saurapod-like dinosaurs that didn't have elephant like feet either.
Also on the flying machines... the Mayans have flying machines carved on their tombs... or at least that's
exactly what they look like. Ancient South Americans may have had flying machines. I have no Idea if they actually did or not. I also know it's common to think that since this is the age of F-22 raptors, and xbox live that all ancient cultures were blatantly uneducated/unadvanced and couldn't really do anything except make Temples with pictures of Flying Machines because they wish they had them/had absolutely nothing better to do... yes I know it's a bad run on sentence, but you understand the modern mindset.
Plus these flying machines would explain the Nazca Lines. Again, all I'm looking for is solid evidence. So with that said,
The evolutionist have no real solid evidence that these South Americans did not have advanced technology/ co-existence with dinosaurs. Only suggestions and assumptions. I can only assume that either:
A. Evolutionist are too lazy to actually research the subject, and they might miss a few episodes of American Idol.
or
B. Evolutionist are too biased/prideful/know it all/ we are better than you (mindset) to actually research the subject when they know full well that they have the funds to actually do a tiny bit of research that would help the community out as whole.
or
C. Evolutionist know these findings would totally rock their world, and put their entire World View at stake. So they just sit back make fun of these Stones/ Tombs/Sculptures without doing any actual research because they have the money and funds to do nothing but publish articles to make fun of these findings. They have the upper hand ( Government Funding) and they know it.
So, all I want is real hands on factual evidence that the evidence presented here in this thread is fake. That's all I want. Just prove it's fake. It should be as easy as taking a Vacation to South America. I want to know it's fake.
Show me the dremel tool that carved into the stones.Show me the fold out chairs the farmer sat in to carve the stones.Show me the Crayola finger paint that was used.Show me the 3M wet or dry sandpaper that polished the Stones, or a buffing wheel.Show me the bakery that made the Clay Sculptures, or the Crayola ® clay that made them.All they need is a few simple pictures of these objects. They can use their Cellphone to take the pictures, or they can use a cheap gift store camera.
It's simple really for evolutionist... just show it's fake. It really isn't that hard, but the heresay, suggestions, and assumptions simply are not enough to shove these findings under rug, or to label them as hoaxes.
Just show them as being fakes, and that's all I want to see.
