Seeing faces, animals and other things that aren’t there is called pareidolia. The propensity probably goes way back. It’s thought to have played a role in ancient imaginings of Orion the Hunter and other constellations.

Even monkeys do pareidolia, lingering over images of inanimate objects in which humans had spotted illusory faces.
