So I've been watching the show Ancient Aliens which I think is a fascinating subject and need to have an open mind but in all honesty I just think the guy who probably didn't start all this but popularized it Erich von Daniken has one big imagination and possibly out of his mind. I just think historians and others alike do not give our ancient ancestors much credit for the possible technology that they could have had in the past before their civilization disappeared for whatever reason. Just because who have not found any blueprints or records of how they built some of these incredible buildings and structures doesn't mean we were visited by life forms from outer space. But what do you guys think? I just think this whole idea of ancient aliens visiting us in the past is full of baloney but is interesting to think about it in science fiction terms.
