Features: Whenever people gaze at the vast sky, seeing the countless stars scattered across the velvet-like night, a sense of human loneliness arises. They can't help but wonder if, besides humans on Earth, there are also intelligent life forms on other distant planets. As early as the 4th century BC, the ancient Greek philosopher Metrodorus once said, "The idea that only on Earth are humans living in the boundless universe is as delightful as a single grain of wheat growing in a field of harvested crops." In fact, extraterrestrials from distant planets have been visiting Earth since ancient times. They are the neighbors, friends, and even, in a natural sense, the siblings of Earthlings. Therefore, it can be said that in the vast universe, humanity on Earth is not truly alone; "our friends are all over the world." This book explores UFOs and extraterrestrials from six chapters: "The Shapes of UFOs," "Falling UFOs," "The Flight Principles and Power Sources of UFOs," "The Kinds of Extraterrestrials," "Entering a UFO and Exploring Alien Planets," and "Space Romance." Through various perspectives, it provides a general exploration of UFOs and extraterrestrials, serving as a stepping stone for further discussion.
