I have been to the Great Pyramids and several of the Mexican ones as well. The size of them dwarfs the mind and these Bosnian ones are colossal compared to them. My problem is that there are several answers that are left open. Where were the stones quarried at and where is the evidence of this quarrying activity? Where did they get the manpower to build them, is there demographics about the population of the area to back up the pyramid theory? Where are records of such building, how was it accomplished without written language? I’m skeptical about this theory and will need several years of archaeological digging to prove they are pyramids.
