So basically a tree doesn't fall in the forest if there's no one around to see it? There's no forest and there are not trees. It's all spawned as needed when we go for a hike? Kinda arrogant don't you think?
A tree interacts with many things, not just human observers. We are not special in any way. This discreteness is only relevant and/or observable when we look at individual particles that rarely interact with anything else.
