text: First of all, no one has seen anything like this before. The text states," There must have been a degree of surprise among mission controllers back at the Jet Propulsion Lab when the face appeared on their monitors." This peice of evidence shows that the face is new to them, and they don't know what it is. Another piece of evidence is," Twenty five years ago something funny happened around Mars." This, also, shows that NASA doesn't know what it is. If no one knows what it is then you can't say it is a human or alien without knowing the facts.
