I am fascinated by the Magdalenian period and what appears to me after some research, the very strong possibility that the Earth at that time was home to a society that had long distance travel, higher technology than we have been led to believe and possibly even regular interaction with other planetary societies. It seems like cognitive dissonance to think that the people who painted Lascaux may have had access to a spaceport;-) but living in Florida shows you that things far too weird to be believed happen ALL the time!;-)
