Martians is the name for aliens from the planet Mars. They are often shown as green but there is no evidence that they exist. Martians are a key in many space movies. One of the most popular was Mars Attacks!, a comedy/science fiction movie about near indestructible aliens who come and destroy most of the United States (they are destroyed by Yodel music.) Martians are also featured in many Science Fiction books.
