Yeah, pretty sure he is. He kinda has a point in a way. There are certain myths that seem to be nearly universal in human societies. Cultures all over the world have stories of the great flood (there have been many, just not the biblical type) and giants, many things seem to pop up in cultures which were completely isolated from each other. My favorite anthropologist, Joseph Campbell, has a great book that deals with this phenomenon called "The Hero with a Thousand Faces". To crudely sum it up he basically says that humans all over the world have basically the same unknown question to struggle with and the same types of internal/societal conflicts and maybe most importantly we all have the same brians. That is, the physical seat of our consciousness is the brain and it is anatomically the same for all races. So it makes sense that we would come up with similar myths to deal with these issues.
