So much has been theorized about UFO's and the possibility, however vague, of us being created by extra-terrestrials in a lab that the eye has been taken off the ball. As we have developed space technology in a few thousand years, then why could our most distant Ancestors not do the same things over the space of millions of years and many successive Ages? There is a lot of evidence to suggest that our recorded history is but a drop in the ocean, and that most of this history hasn't been told. My belief is that our prehistoric ancestors were not dumb, or less advanced than we are in this current Age of Civilization. EM propulsion was used to power Vimanas, or flying ships of all kinds. These ancient "UFO's"- and the pyramids - were designed and manufactured by human beings, not aliens. Just my opinion anyway....here is a video by Prof. Simon Holland on aspects of EM technology, both past and present future.
Hard evidence of advanced stone masonry works that the dynastic Egyptians could not have done using rudimentary tools. These out of place artifacts can't be replicated even nowadays by the best craftspeople using the best equipment. To my way of reasoning then, it must have been the case that whomever made these items out of the hardest and most difficult to work rocks and crystals must have had a good reason to make them. They obviously had a specific function or functions. And, these prehistoric peoples had the means to fashion the stones from raw bedrock, move the stones around (some weigh tens or even hundreds of tons), and shape them to unbelievable tolerances.
By applying rays within of the electromagnetic spectrum to stone, the structure of the internal matrix of the stone can be altered. Lazer technology and/or power tools certainly seem to have been used to cut and shape the stones.
Thank you, Zephonith.
