Video of man erecting 20-ton block from horizontal to perfectly vertical by himself. Same technique could have been employed in erecting Anciet Egypt's gigantic obelisks.
Amazing demonstration, however does not explain how these monoliths we're cut and quarred at times from hundreds of miles away.Or hoisted fifty feet in the air, and fit with flawless percision.Or advanced astrological knowledge.As well as astounding architectural knowledge that was used with the great pyramids.Truth is what the facts are, there's no evidence of God or aliens and I don't believe in either. My personal hypotheses is ancient civilizations where far more advanced then what we know.All evidence such as tools are none exsistend cause of time and or natural cataclysm.Much the same way the Titanic at the bottom of the Atlantic for only a hundred years has almost he wrote it and did nothing and will be non-existent in another hundred or so years.I think the last cataclysm we had 12,000 years ago wiped out all of the evidence of how these monoliths and incredible structures were built,truly an enigma and we may never find out exactly how it was done.but one thing for sure all these magnificent temples, pyramids, monoliths,all signs of advanced civilization. If this gentleman would like to impress me cut and quarry and build the Temple of the Moon that we find in Bolivia.
