    Look around the space you’re in and notice that you can’t “see” the light, only the things.

          It is literally activating the rods and cones based on photons hitting them. Do you think we don’t smell smells either?

          Ah yes, that’s famously why screens literally build tiny versions of the world inside them. We don’t see the light, we see the objects!

            The light that enters your eye carries enormous amounts of information with it. Your eye and a small portion of your brain comprise a highly specific tool for extracting a small subset of that information and processing it. The information you use is only related to the last object the light interacted with, not the light itself (with the small exception being the “brightness” - that has nothing to do with the object).

            No one claims to hear the air in their ears rather than the violin that is being played nearby. That’s just not what the word “hear” means.

              This is obviously false, otherwise all objects would look the same under any color of light - yet they don’t. This example actually shows that it is only the light itself that matters, because it has the information of the objects it interacted with during its lifetime!

              No one claims to hear the air in their ears rather than the violin that is being played nearby. That’s just not what the word “hear” means.

              But everyone would agree that we’re hearing the sound waves produced by the violin. Again, a great example counter to your point, as the equivalent to a sound wave is the photon.

        You can’t see light. You can see things illuminated by light.

            That’s it. And, indeed, you see light. That’s what your eyes do.

            Little smart ass knowhow: With your hands, you can feel light.

            You feel infrared light as heat. Not visible light though. Just heat up your cooker stove and it emits a bit visible red and a lot infrared light. Don’t touch just keep your hand close to the stove. Now you feel the IR-„light“.

            Or just take an IR-lamp for your neck pain. You‘ll feel the light that’s emitting with your hands.

            That’s not what the word “see” means. You’re trying to to swap it for another word like “sense.” You see objects, not light.

              Bro, take the L and walk away. Seeing is a sense, senses are neurons activated by something, whether it’s; temperature, chemicals, or photons.

      Imagine if they showed real physics in sci-fi movies. You’d never see any laser blasts in space, just the result of their strike.
