That you can only see the question in one light is not our fault.
This has been a philosophical debate for centuries, if not millennia.
But sometime in the 19th century it was posed as more of a scientific question regarding sound, and not philosophical (and certainly not at the quantum physics level). Scientific American was one of them. "“...sound is vibration, transmitted to our senses through the mechanism of the ear, and recognized as sound only at our nerve centers. The falling of the tree or any other disturbance will produce vibration of the air. If there be no ears to hear, there will be no sound.”

If you want to see it only from the philosophical, excellent. Others don't. Sorry this has crushed you to the point of tarring this site. But I won't call you ignorant.
