Interesting concept. I really wonder what the scale of this cross is?
It's big. Much bigger than a screw head. Anyways, the screw head couldn't have left the circle imprinted in the middle of the cross, so it wasn't the screw that made it.
Not saying it was aliens but it was definitely aliens.
Haha, I love that reference.. but then again, maybe it wasnt just aliens.. I hear now that it could be ghosts along with aliens.
Anyways, definitely some strange stuff on mars. It's hard not to see things that your familiar with.. on par with seeing animals in the clouds. I still believe that there is about a 60%-70% chance that there was some form of life on mars, intelligent or otherwise.. Considering we and whats on Earth is the only life we currently know of, it makes sense that if there is other life out there.. the apple shouldn't fall far from the tree. There's a better chance of finding it close to home versus some far off place we can't see or reach.. a lot of space out there.
