How could illumination make human history?

Where was the screen for illumination images?
Human being's eye.
Pupil. Human beings are all pupils with pupils enlightened.
We can see the trick mechanism easily.
In the darkness of a big case like a dressing case, we can see a screen images projected through a pinhole from the outside.
Pinhole cameras go in the same way.
Human being's eyes, too, go in the same way with the dressing case pinholed.
Now natural light is not used.
So, human being's eye is not used for the screen.
Electric waves are projected into the back of a head, the range of vision, from underground.
But, not a very important contrivance, today.
