I never watched that show the Coneheads, but I think about dunce caps (conical) that many saw in cartoons and books growing up. Was it a form of mocking? That seems to be a strategy that is used a lot against humanity. Perhaps these individuals are not actually the enemy, or why would so much ride on keeping them hidden or distorting this archeological information? Is it possible one group is trying to eradicate them because they are a threat to the group that wants total control? (I know people like the shadow rulers/puppeteer idea, but I think that might be a distraction.) They measure infant and toddler heads now and I consider that, along with the amount of effort that goes into maintaining the evolution theory when there seem to be examples that challenge it (the RH- group, the advances in genetics that demonstrate chimeric DNA, etc.). Interesting area of inquiry for sure.
