I would say anything found in South America is worth viewing. There are murals in Egypt and the middle east which have survived on walls for thousands of years, so It's possible for these murals to be legitimate. Even if they are not at least there is no denying that this place was once cleary heavily populated during the preflood civilisation. The lastest flood that is (11500 years ago). There are remenants of cities under the Amazon. Had you flown over the amazon 12000 years ago at night, I bet you would have seen as many lights as you do over Europe today. And you would have seen space ships taking off as well. Brien Forrester, Graham Hancock and others speak a lot about South America. Farsight have proved some of this. Many species in the Americas appear to have been wiped out overnight whilst those in Africa appear to have been largely unaffected suggesting the Americas were the epicentre of a possible meteor strike/attack which melted the ice cap and caused that particular flood. It looks like they have drawn some of them, like the giant sloth.
The Satanic Catholic church, pedo Columbus and the conquistadores had a reason for totally ransacking the place, Killing the people, destroying evidence and bringing much of it back to the Vatican where they have all the documents/maps etc from the library of Alexandria. Unluckily there for them there is way too much evicence still there including the multiple pyramids. Some with Mercury found in them, one of the power sources for the global Pyramid grid. The murals now further prove the mainstream rubbish pedalled to us by Masonic controlled evidence suppressing archeologists and so called Historians is false. There have been people there for hundreads of thousands of years.
