Original mirror : the image we have of the outside of our brain world is created in our brain. Brain is a closed black box, image is created inside through electric signal transmitted by the eyes.
You could see a lion simply if we could send the right electric signal in the optic nerve, but this lion wouldn't exist anywhere else than in your brain.
First mirror is something between outside and inside,.
Fire starting looked like induction heating process by electromagnetic waves with specific frequencies.
