I don't disagree. This actually has a place on the technology scale. But sadly, it's all too often pushed by smooth brains as a solution to every megalithic problem. Many people accept that technologies like this are the answer. Of course they accept it because they've never actually looked into it. That's the purpose. This is in fact the case of stupid bird. I name him because simply asking him to research more into the complexities of the ancient megaliths resulted in a block. Yet his smooth bird brain behavior is textbook for those indoctrinated by this type of propaganda. There is a concerted effort to trivialize the complexity of issues so that it can fit the historical revisionism. Example, Egyptians or blacks built Egypt because it's all so simple - see. Never mind the current Egyptians have only been there 700-1000 years and blacks have never built anything. By obfuscating the technological burden required of mainstream impossibility (meaning the technology mainstream allow existed) of these ancient megalithic structures, it significantly eases the burdens on those who would revise history to suit their agendas.
