If everything comes from the universe then why do you think you own you?
Also, in my opinion you are monumentally more important than the earth or the universe or a mountain or a stream. You will only exist for a brief time. The mountain and stream will exist for ages. And when they are gone then will not care, as they do not care today.
I have never met you, but understand, if someone said I could save your life, even just for a year or two, by lopping off the top of Mount Everest, I would do it in a second.
It's just dirt.
There is an entire fucking universe full of dirt and mountains MUCH higher. I'm literally serious, mountains are a dime a dozen in the universe. We don't need to save mountains. Compared to the uniqueness that is you.
There is only one you, and when you are gone, Mount Everest will not comfort your friends and family for the loss.
