No,the best theory is they cut the stones in a slightly underwater quarry. The limestone if submerged hasn't gained co2. They used a complex system similar to a canal. They used ballast like logs or airbags to float the cut rocks while keeping them uderwater. Even the top working row was a water filled mini canal. They would drop the stones into place. Once the water was removed the limestone would absorb co2 and swell, tightening the blocks together. This would have been some serious engineering.
