No matter how the scientists and skeptics try to explain it, it looks like a person or statue to me! Remember the pictures that Mars surveyor took at low altitude of the "face" and the "pyramids" on the planet? Scientists tried to explain them away too and didn't release them until they thought they had a believeable explanation. Same here since this picture was taken in 2004!
I have always believed that NASA is finding things in the solar system that they would rather keep quiet about. That would explain why 25 years ago, scientists were saying there was no life anywhere but here; now they have turned 180 degrees and are saying extraterristrial life is everywhere!
They are getting us ready for something!

Rock or alien?
How about a third option? Isn't it possible that it is a statue or something simalar? Like the "Face" on mars could also be? Maybe it is proof of an anceint and extinct civilization on mars? Maybe a long time ago mars was a lot more like Earth and maybe our ancestors even came to earth from Mars when the planet began to heat up and loose its water, just like we might have to leave Earth when global warming starts to kill the ocean?
