Paranormal and Alien Lore Editor

The Ancient Astronauts have always been an interesting and even tantalizing theory. You may remember, if you were alive in the 1970's, Erich von Däniken's books--like Chariots of the Gods--that claimed the ancient astronauts gave us important technologies and enabled us (or even did it for us) to build monuments like the Egyptian pyramids, Stonehenge, and the Moai of Easter Island.
Generally, ancient astronaut theories postulate that we were visited thousands of years ago by Visitors. Some alien lore goes so far as to speculate that not only were we visited, but that we are the fruit of seeds planted by these ancient astronauts. In short, our great great great great grandparents were Greys or another form of alien who not only populated the earth, but left behind clues that would eventually enable us to fly and practice medicine and other sciences. This theory is shaky, considering that bloodletting was still standard medical operating procedure up until the late 1800's. Only around the same period did we realize that hand washing and sterilizing surgical instruments would prevent infection and death following surgery.
