Because physics, optics, and physiology (and math) govern the physical laws regarding the light being reflected off the plane, going through the convex lens of the eye, an forming an image on the 2D surface of the retina.

Because, as I also explained, how the brain interprets the information coming from the optic nerve depends on all the other images in same frame as the model, what that particular brain already "knows" about the object and environment (cognitive bias), and the heuristics developed by that individual over their life to speed mental processing. Two of those three vary greatly by person, thus different interpretations of the same image. In fact there's quite a lot of academic research on it ... I've appended a couple links on the subject of mental shortcuts ... heuristics, cognitive bias, and decision making (i.e. "Is that roll 'scale'?).
