I love your dismissive and faux superior attitude especially when claiming knowledge not your own and using it to attempt to deride someone who worked with Manhattans biggest real estate developer for 15 years, giving me access to talk with the most up to date, state of the art General Contractors about building techniques; it says a lot about you. But you're right Miss Scarlett, I'm a house worker, I don't know nothing about building large buildings.
The man in the video is clearly onto something, no doubt about it. He moved those large stone all by himself around his level, concrete platform with the greatest of ease.
Since the quarry for the Stonehenge Blue Stone was over 240 miles away all we have to do is find the portions of the overland level concrete road that eased transportation of the stones from the quarry to the construction site. Piece of cake.
I was thinking more about the following: Puma Punku where the stone clearly show signs of complex engineering and machines cuts. These were not done with deer antlers.
And then at Sacsayhumana where they took the mans stone moving techniques and added a dimension to it because some of the stone have as many as 16 facets and they fit absolutely perfectly into all of the stones next to them.
The explanation that the Baghdad batter was used for electroplating gold jewelry makes less sense than anything you've posted, but again, since that explanation is not your own, I cannot fault you for it.
I'm more inclined to go with the idea that mankind was as clever then as we are today; that back then people were as smart as Einstein, Obama, Old Rocks and Freddo Corleone and they may have come up with more practical uses for electricity then pawning fake gold coins off on people.
This is from the Egyptian Temple at Dendera and shows a construction that looks an awful lot like a light bulb. This would make sense that the interiors of Egyptian temples were artificially lighted since no system of mirrors was capable of bringing sunlight into the temples while they were being built and no smoke from burning torches has ever been found on the ceiling of the interior of any Egyptian Temple. The Bablyonians and Egyptians and countless others all knew what power there was in lightning and found a way to harness electricity for their purposes.
We forgot somewhere along the way.
