text: NASA is a professional agency, why would they lie. In the passage it says "Some people think the Face is bona fide evidence of life on Marsevidence that NASA would rather hide, say conspiracy theorists. Meanwhile, defenders of the NASA budget wish there was an ancient civilization on Mars." Therefore, why would NASA keep that information from the people when it would actually benefit them. If NASA says that the Face is just a land form and only looks like a face because of the shadows, then it obviously is.
