There's an old brain-teaser of sorts: "If a tree falls in the forest and nobody hears it, does it still make a sound?" People can have a few moments' mind-sport debating over whether the "sound" is the air-carried disturbance or the perception of it, debating whether we can prove a thing with no witnesses, debating whether it matters if nobody is aware of it.
In relation to God: if there were no creatures capable of perceiving awesomeness, would God be an awesome God? If God had not created, he would not be Creator (or Redeemer, or Sustainer). If there were no Time, he would not be Ancient of Days. If there were no creatures with families, he would not be Our Father. If there were no earth, he would not be Our Rock. If no one could see, he would not be our Light; if no one had ever walked, he would not be our Way. If there were no minds to perceive reality, would not be our Truth. If he were all that existed, he would not be the Lord of Hosts. Without a flock, he would not be the Good Shepherd. If there were no places, would he be Omnipresent? If nobody else existed and nothing ever happened, would it mean anything to be Omniscient? If he never did anything, would it matter whether he were Omnipotent? Without creation, God could be compared to the tree in the forest -- the one that nobody heard.
When God said, "It is not good for man to be alone," I wonder whether he spoke from experience there. Without Eve, then Adam was the tree that fell in the forest. And as God sends us to love our neighbors, I think that's part of what we do for our neighbors. We see them, we know they're there, we take notice of them, and when they fall we remember them. The more we do that for our neighbors, the more they matter. So they are not the tree that falls in the forest, and neither are we.
