Not really. But it did send back this image of what appears to be a long-haired woman, wearing a dress in the rocky outcroppings of the red planet.
So, that's proof right?
A least, they think so on ufosightingsdaily.com
Its hard to tell if this is a living being, or a statue of a being from long ago. However, a statue that small would be eroded and destroyed easily, so it has a higher chance of being a living being. Also it is facing the Mars rover...watching it from a distance. This being is about 8-10 cm tall. Yes, one such species is known to exist that small.
Well. Um. That's one opinion.
