Was there ever life on Mars?
Well alien hunters have been sent into a frenzy following a NASA picture taken by Curiosity rover on August 14 which appears to show a crooked thigh bone.
Space-alien theorists are hoping it is the proof that little green men did exist at one time but NASA, on the other hand, continue to shatter their dreams.
Believing that it is a rock shaped by the wind and nothing more, a NASA statement said: : "If life ever existed on Mars, scientists expect that it would be small simple life forms called microbes. Mars likely never had enough oxygen in its atmosphere and elsewhere to support more complex organisms. Thus, large fossils are not likely."
What do you think?
