The Tower of Babel

[Huggy Bear]

Second of all look up Coral Castle.

The guy who single-handedly built that (which required cutting, moving and erecting stone up to 30 tons form a quarry 10 miles away overnight) claimed he used the same technology used in building the pyramids.

Claimed.

Many stories and wild theories emerged over the decades about Leedskalnin and how he built his castle. Some say he levitated the blocks with psychic powers, or by singing to the stones. Others suggest Leedskalnin had arcane knowledge of magnetism and so-called "earth energies."

As tempting as it is to view the amazing park through a veil of mystery, in fact we know how the castle was built. Creating a structure like the Coral Castle today could probably be accomplished in a few months with a construction crew and modern machinery. But Leedskalnin worked alone using basic tools like picks, winches, ropes and pulleys. Leedskalnin himself said that that he did it using hard work and the principles of leverage. The tools he used to quarry the rock are on display at the Coral Castle, and several old photos depict the large tripods, pulleys, and winches he used to move the blocks. Though the quarried stone slabs are large, they are actually lighter than they appear because the rock is porous.

Remarkably, when he heard that a subdivision was being planned near his home, he bought land 10 miles away. Over the next three years, he moved the structures he had already begun from Florida City to Homestead, according to the museum's website.

Though Leedskalnin worked alone, he was not a reclusive hermit; he had friends who he saw often. One man, Orval Irwin, was not only a long-time friend of Leedskalnin's but also a building contractor with a deep knowledge of construction techniques. Irwin wrote a 1996 book with the inspiring title "Mr. Can't Is Dead! The Story of the Coral Castle," and in it he explains, through photographs, drawings, and schematics, how it was done.

Irwin pours cold water on the paranormal theories that unknown energies, alien technology, or levitation built the castle. In fact, he finds such theories an insult to the hard work and integrity of his friend: "Back in the days when Ed started carving out his original stones," Irwin writes, "his was a generation who knew accomplishments by the sweat of the brow. It wasn't mysticism but hard work, this is how Ed really accomplished the massive project...."

The things that are abundantly clear,are that Leedskalnin worked alone, at night, and that no one ever saw his techniques.

Feel free to explain how a single man can move a 30 ton stone 10 miles overnight, using the took mentioned.
