Pink Face Peering Out Of Cave Found In Mars

An image from planet Mars taken by NASA's Curiosity rover shows the figure of reddish face peeked out of a stone cave, looking directly at the rover. 

This anomaly was discovered by Scott C. Waring from UFO Sightings Daily. He said "Right inside this little cave area there is a pink face or a red face sticking out."Is it a living being, possibly.
