Why are archaeologists certain that metal was not used in making the pyraminds of the Yucatan or S. America?

Question

What types of tests have been conducted to show that there are no microscopic metallic particles on the surface of the pyramid structure? Or have they based their conclusion on the fact that very little metal objects have been found? If this is true, could it be that the metal tools or objects were melted during the invasion of the Spanish to make coins or metal weapons?

Answer 1

Metal was used the pyramids all around the world. They were generators... water would run these generators and the generators would produce electricity. It was a alchemy 'transfiguration' machine aswell. Look at this video to see what I mean.
