Forget the pebble skulls of action men sized pygmies carefully created as a story to help you forget all about this picture - how long will it take you to spot the obvious here without your fevered brain finding a face in every anthropomorphism ? Disinfo artists forget how intelligent most people really are. Be honest if you went through this picture pixel by pixel to find some sort of skull at a certain resolution and magnification - you could not have missed the crash debris. Mind you its probably debris from one of the many satellites sent there but which crashed on deployment - certainly of an interesting and resilient metal. No doubt NASA will be curious enough to test its composition with their onboard spectroscope ... I would be curious to find out about that metal - wouldn't you ?
