A Foo Fighter is this like orb or saucer that flew around Allied aircraft in WWII. I read that they are extremely difficult to kill and have great agility. Nazis did crazy things. It seems Hitler was interested in many paranormal things. If you look up Sumerians and Aliens they had a weird creation story. It was about two forces that battled before mankind. One was the Elder and the other the Ancients. The Elder slew their Ancient brethren for control of our world and created man as a slave race to do their work. Seems like a load of it. I think the Elder may be aliens and I think the Sumerians were lied to, but they did possess a curious amount of knowledge on solar system and the way it works. I would have previously argued that they were just a bunch of crazed witches but that is not likely. They made figures depicting the android like beings. Rumor has it that these drone like beings teach their human allies how to do all kinds of stuff we couldn’t even image. If you believe the Sumerian legends then these visitors return every 3000 or so years. We could already be on other planets and not know it if these visitors took Sumerians as “slaves.” I mean most people think aliens when I say Area51. Some probably stayed behind. Something about planet X which is another earth like planet on some sort of weird orbit path.
