Chance of being a real sculpture head: 98%

I found this face and posted it, a few days later it went viral, because they said it looks like President Obama. 

Searching for structures on Mars I found this head. From the way its standing up I would say that it is a full statue, but is buried from the shoulders down. Its standing perfectly upright. It looks humanoid, but hard to tell with a sculpture. Most people are calling these rocks carvings, but I highly doubt that this is mere rock, but instead is probably a 3D printed substance with tech printed inside. Sure we see scatterings of rocks, but it may just be the remains of an alien civilization that was hit hard by a competing alien race. Sure hope humanity never discovers such weapons.

Photos description states:
This is the Spirit Pancam "Everest" panorama, acquired on sols 620 to 622 (October 1 to 3, 2005) from a position in the Columbia Hills at the true summit of Husband Hill. The summit region is a broad plateau about 100 meters (300 feet) above the surrounding plains of Gusev crater, consisting mostly of outcrop rocks and windblown drifts. The distant view in the center of this mosaic is looking from the summit into the South Basin, the region where Spirit will be driving down into and exploring over the coming months.
