Aliens Did Not Build The Egyptian Pyramids
There are plenty of theories about how the pyramids at Giza were built. The opinions range from plausible explanations based on the tools and understanding that we know the ancient Egyptians had, all the way to fantastical accounts about how aliens had to have constructed them. Of course, Ancient Aliens falls into the latter category.
The directors of Ancient Aliens claim that the blocks used for the pyramids and other structures built by the ancient Egyptians had to have been cut using laser beam technology. Nevertheless, this claim is incorrect. Researchers have proven time and again that even the hard granite that the Egyptians used for some of their structures could have been cut with the very human tools that they had available.
