When I was just two years younger than this little mensa, I saw the "Chariots of the Gods" movie, narrated by Rod Serling.
I was absolutely convinced that ancient astronauts had built the pyramids, had taught the Incas to fly spaceships and would return, according to an old Aztec calender, on December 23, 2003.
Remember the Nostradamus movie with Orson Wells? Remeber that huge Earthquake that wiped out LA and San Fran in 1987? Wait a minute, that didn't happen! Stupid Nostradamus!
Hey, if the Incas had spaceships, how'd Pizzaro take them so easily? Maybe they got the death ray button and the "deploy cupholder" button confused in the heat of battle.
