> Molecules touch your nose and you smell things. Air vibrates your inner ear hairs and you hear things. Photons hit your eyes and you see things (not sure if this counts but it seems like it could).

You can see things in the dark with your eyes closed, you can hear things in a vacuum sealed isolation chamber, you can smell things without any there being anything smelly and you can feel things without touching anything.

Rather than every sense being touch, every sense seems mental.
