how?.....those structures that they take you too......do they not exist?....and how is their theory that Aliens helped build them crazy?.....whats your theory?......
Those structures they take you to and say.....No humans could have built this
Meanwhile they ignore scientific explanations of how it could have been built
Quasi-science
There is a site that was built with natural stone. EVERY block was a different size and shape and no mortar was used. It's still standing today and even today the joints are so tight a human hair wont fit between the blocks.
I work with stone every day and I have all the top of the line tools. Laser guided diamond saws etc and I can't even come close to that kind of craftsmanship. And the stone I work with doesn't weigh tons.
With the technology they had this was impossible. Not to say it was aliens but it sure as fuck wasn't some dude in a loincloth with a stick and a rock.
