Tree


Well, in your scenario, you are a human, and you are the one making the sound. The condition in the tree scenario is that no living things are around

existing is different from hearing. It's like you're saying 1 is the same is 3

If a tree falls in a forest, and no one is around, does it make a sound?
Yeah, cause the squirrels definitely heard that crash

If no one hears the crash, there’s no proof it happened, so it’s unknown. But since we always hear a sound when a tree falls, we assume it still makes a sound even if no one’s around. Then, maybe the tree only makes a sound if someone’s there to hear it...

a sound is a concept formed by your brain, because your ears detect the vibrations in the air.
it makes vibrations, both in the ground and the air, but that is not sound.
again, the sound is made up by our brains, and other creatures brains, and therefore is not truly real

You're being picky about the word "sound", but the core of the OP's question can be rephrased as: "If a tree falls in a forest and no one is around, does it make a vibration?"
And then, the question still leaves room for debate...
