Please examine the monolithic enormous stones and inform me that you have the technology to raise them. Even with today’s powerful cranes, we can’t lift some of these big stones.
If we can’t raise them, how did past civilizations do it?
As Vulcanian Spock would reply, there is only one reasonable answer: they did have some levitation technology. According to what I’ve learnt during many years of research on this subject, the ancients had two methods for lifting such big stones.
The initial method was the use of a sound-based technology.
Sound is actually vibration, and you may accomplish levitation by surrounding anything with a very exact sound of a very specific frequency.
The other strategy is based on the brain’s power. Have you noticed the elongated skulls? I believe they have telepathic abilities and, as a result, the ability to levitate objects.
