In his defence on that term, he is a regular on the show Ancient Aliens as most know. I find that many of those theorists tend to use terms that cater to the public when they are trying to explain something with a dumbed down "explain it like I'm 5" mentality. I too have heard him and others use star wars or space TV/movie type terms but I truly think they do this as a way to simplify what they are referring to or talking about. I'm not a fanboy of him and I've only watched a handful of his videos but right now I'm at a mindest where I'll give any theory a chance at least once and then discard the truly stupid theories etc. But I do believe those terms him and others use arent direct quotes always of what they believe are alien term names etc.
