If a tree falls in the forest with no one around to lick it, does it create a taste? If a tree falls in the forest with no one around to see it, does it construct a vision?
It seems to me that a falling tree can never make a sound, even if someone IS there to hear it. Falling trees make vibrations, not sounds. Eardrums make sounds by reacting to the stimuli of vibrations.
Likewise, falling trees don’t make sight nor taste either. For the eye to see, photons bounce off of matter and into the retina, whereas the optic nerve reacts to stimuli and thereby creates a vision. For the tongue to taste, chemoreceptors (taste buds) react to chemical stimuli and thus transduce them into electrical action potentials for the brain to interpret as flavor.
So regardless of whether or not a person is around, trees can never make vision, taste or sound. Humans do these things by reacting to the various stimuli around us.
