RCJ, count me a big fan of Erich, just I treat it like science fiction. Problem is too many people think it is history. Apparently the History Channel does as they have given him voice again on Ancient Aliens. I may be a chemist, but I have a history degree too. I love to watch Ancient Aliens just to get my Blood Pressure up, ticks me off every time.
i did like the episode about the potential Alien crash in Texas.
I don't think we are alone in the universe, but if the aliens are more advanced, they sure don't want to come here on vacation.
