I think it's completely subjective, because it depends what degree of specificity you are edging on. In one extreme, plenty of people are convinced they see animal and even human like figures in the Martian landscape photos. On the other extreme, under a microscope, no two rocks look exactly alike, let alone like humans. That subjectivity of scope, I think, clouds our ability to grasp the complexity of the subject, and our ability to discuss it from an objective perspective.
