No joke. When I’m hiking, I see distant rocks that look like animals and other shapes all the time. It’s also common to see patterns in rock walls. Sure enough, when I actually get there, it looks like something totally else (usually nothing remarkable at all). The human eye and brain are very easy to fool. The face on Mars only looks like that when the sun is hitting at a certain angle. I’ve seen pictures of the same region with the sun hitting at a different angle and it looks like just a bare patch of sand with some rocks strewn around. It’s sometimes fun to look at stuff like that out in nature and see what appears as long as you keep your perspective about it.
