News in a flash—Nostradamus, a French physician known for his vague but intriguing predictions of future events, predicted the arrival of aliens—or maybe something else. An excerpt from his book, Les Propheties described an event that most experts believe as alien invasion: "Twinkle, twinkle, little star. How I wonder what you are. Up above the world so high. Like a diamond in the sky. Twinkle, twinkle little star. How I wonder what you are." Many scholars believe this is the arrival of aliens in our night skies. We couldn't wonder about stars because we already know what they are, so they must be something unidentified for us to wonder about. Other scholars on the other hand, argue that they are comets or planets closing in on Earth's orbit, because UFO's don't usually twinkle as much as heavenly bodies such as stars and planets—though they are extremely bright, but Nostradamus clearly described the objects as twinkly.
