Greek Head

I always thought only the Romans and maybe Egyptians have been to Mars before. Obviously I was wrong! So far I did not spot any Egyptian traces but, contrary to all my believes, Mars is Greek :D.

When I first saw it, it looked a bit like Chewbacca; that was before I blew up the resolution, now we can clearly identify it as being greek.

There is one thing that I am not sure about in this. Although it obviously is Greek it has features that remind me of the Borg in Star Trek. This puzzled me for quite some time and I needed a rest to come up with a plausible theory.

The only way this could have happened is that the ancient greek were assimilated 2.000 years ago, lived on Mars for a while and left some of their Borg-statues, which are slighly weathered by now.

As to when and where to the Borg-Greeks left Mars, I am still trying to come up with a theory, so far i have none. 

Any other theories? Please help me :).
