I have always been interested in something related to aliens and the universe. I also know there is a place where all alien fans want to go on a pilgrimage is called “ Area 51”. Not long ago, I read a book about "Area 51" which is in a desert of Nevada, USA. The book mentions that allegedly the body of an alien named Roswell has been hidden in this place. You may wonder why the alien is called Roswell. That’s because the alien piloted a UFO and crashed around a small town named Roswell in the area. Hence, people called it Roswell. Regarding Area 51, you may also wonder why people call it this name. Since 1944, the area was originally an air base for testing newly developed aeronautical equipment and stealth fighters (including nuclear tests). It is marked as Area 51 on the military map. Now, this area has become the most popular pilgrimage site for alien fans. There is even a highway here called Extraterrestrial highway. Allegedly there are many people witnessed UFO appeared here.
