The official stance of NASA is that Mars could probably support microbial life. But some people believe these so called "scientists" are just hiding the real truth. Namely, that there is already life on Mars and if you just look at photos from the Mars Rover you can see it. I mean sure, there's no "science" behind it, but who needs "science" when you have eyes (and photos that were gathered by the best scientific minds in the world who interpret those photos differently).
I mean, some jerk with a Phd and access to all of NASA's resources might say this is just a normal rock, but if that was true then why does it look so much like an iguana?
And yeah, could this be some dust flying in the wind getting caught at an unusual angle? Sure. But isn't it more likely that there's a human-like woman hanging out on Mars by herself?
And if there's no "life" on Mars, then how did a World War I helmet get there?
Or a rock that's been carved to look like Barack Obama?
So who are you going to believe? Some men and women who are "very fucking smart" and who "work at NASA"? Or are you going to believe people on the Internet who look at stuff? I think the answer is obvious.
You can see more examples of these "signs of life" photos over at CNN.
