Unfortunately, actually visiting Area 51 to try to find out what's happening there is not something anyone can do.

But luckily, there are other places that people can try to find aliens around the world. To see 10 places to search for aliens (outside of Area 51!), keep reading.

10 Thom Reed UFO Monument Park - Sheffield, Massachusetts

The covered bridge in Thom Reed UFO Monument Park, a historical site in Sheffield, Massachusetts, used to be one that cars could drive over. These days, it's simply part of a grassy park and no cars are allowed to drive over it.

This park has been a significant place in Sheffield since 1969 when Thom Reed and his family, while driving over this bridge, saw a bright light come out of the water and then a mysterious force took them to a building full of strange, insect-like creatures. Thom Reed's claim of being abducted was one that even had several witnesses  - 40 other Sheffield residents claimed they saw the same strange light come out of the water.

The Mountain Sphinx is considered one of the wonders of Romania and is a popular tourist destination for anyone visiting the Romanian countryside. This 40-foot-tall rock has been carved to look somewhat similar to a face and is accessible either by hiking or by cable car.

What do aliens have to do with this rock? Some of the  different myths and legends attached to it involve aliens.

7 Point Pleasant, West Virginia

Thanks to a book and movie that were released about this 1966 incident, it's hard to think of Point Pleasant, West Virginia without immediately thinking about the story of the Mothman. Between 1966 and 1967, several different people in the town of Point Pleasant claimed to have seen a tall, humanoid creature with large wings and glowing red eyes flying or following them around town.

Stories about spotting the Mothman mostly stopped after a bridge in Point Pleasant collapsed in 1967, but that hasn't stopped people from speculating. Point Pleasant is now a popular tourist destination for people that want to find the truth about the legend of the Mothman.
