Context: "things must’ve been so hard in a certain way before mirrors were invented"
Consider reflections from water, ice, crystals.
Our ancestors viewed reflective surfaces since the evolution of eyes during the Cambrian explosion.
Mirrors greatly enhance self-viewing, of course.

- Evolution of the eye @ Wikipedia - Many scientists have found the evolution of the eye attractive to study because the eye distinctively exemplifies an analogous organ found in many animal forms. Simple light detection is found in bacteria, single-celled organisms, plants and animals. Complex, image-forming eyes have evolved independently several times. Diverse eyes are known from the Burgess shale of the Middle Cambrian, and from the slightly older Emu Bay Shale. Eyes vary in their visual acuity, the range of wavelengths they can detect, their sensitivity in low light, their ability to detect motion or to resolve objects, and whether they can discriminate colours.
