the problem with ancient a,iens and other shows like it is that, yes, they do bring up a lot of interesting things about previously unknown or little known anthropological and historical issues
BUT
then they go and do the whammy of "it was the aliens that did it!"
thereby throwing all credibility or seriousness over looking at these issues
take the Gobelke-Tepe find
a, by all appearances, neolithic temple complex with very fine detailed stone work and carvings. done at a time when, we are told, man was barely out of the cave.
it is clearly an old,old place and was clearly done by humans on their own (probably because of their high success rate in agriculture and their security factor gave rise to the "leisure time" in which to create such extravagances)-but "Mr Hair" and his fellow kooks just throw it all into the trash pile by equating all of these old human creations with aliens
i put these kind of things in the "lost civilizations" thread
