The idea that music can really only be created by humans is very limiting. Some of the most musical sounds I've ever heard were not created by humans. A few examples:
water falls
a thunder storm, especially with lightning
bird songs
rain falling on the roof
tides crashing against the shoreline
various wind noises
coyotes howling
crackling fire
The natural world provides a myriad of sounds that are quite musical. The may or may not be compositions, but they are organized enough to be readily recognized and they do incite an emotional response.
