There are a number of Unsolved mysteries in the World.
Though Ufologists lists number of UFO ans Alien communication, sceptics have tried to explain them away, but not the following one.
“One summer night in 1977, Jerry Ehman, a volunteer for SETI, or the Search for Extraterrestrial Intelligence, may have become the first man ever to receive an intentional message from an alien world. Ehman was scanning radio waves from deep space, hoping to randomly come across a signal that bore the hallmarks of one that might be sent by intelligent aliens, when he saw his measurements spike.
