How can anyone believe in the nonsense that spews out of NASA! They are BROKE! They NEED MONEY!!! So what better way to try get it - discover alien life forms hidden in a piece of rock from another planet. Oh, that would be worthy of receiving a trillion bucks of wasted tax payers money to divert the scientific funds into some other hidden project, like star wars perhaps? Or better still, the secret research involving hybrid DNA experiments to construct the alien life forms...
NASA is just an emporium of mad scientists and Buck Rogers of the 21st century.
Oh, and regarding the statue of Elvis discovered on Mars, it's not Elvis - it's Gary Glitter for your information. That's obvious by the way the sunlight glitters off it's surface.
