The old man of the mountain is of the same class as the man in the moon. It is a mental construct not a physical object. Different cultures see the rabbit in the moon too. The imagination comes in accepting that random mutations in nucleic acids result in formation of eyes and not in their destruction.
For those who don't have a religious horror of imagination, yes. That, and you forgot to mention the selection pressures.
Out for the night. Way past usual beddy-bye.
