Do you mean all just nerve stimuli? In that case, yes, they're all the same, but otherwise, try and convince me sight is like touching with you eyeballs
Molecules (or photons) aren’t psychic, and our sensory receptors aren’t psychic either. So of course a receptor needs to come into physical contact with a molecule or photons.
I wouldn’t say they are all a variation on the sense of touch, but rather all senses — including touch — are a variation on the stimulation of sensory receptors.
