This is wading into philosophical areas but think about this. We defined what sound is and if there are no biological creatures around to hear a sound or interpret its vibrations, than no there wasn’t a sound. Something fell, a reaction occurred and without an observer there is no sound since there was nothing there when the event occurred.
Also I’m reading more into this and reforming my opinions based on new information so this is an evolving position for me.
Since we devolved to insults. Go fuck your self you fucking wanker.
