Human beings find things other the humans beautiful because we are drawn to what we perceive as beautiful. It may be flowers, dogs, cats, cars, books, coffee shops, or different places on Earth. There is no specific reason why we are drawn to these things, but it may possibly because of our own perspective and hobbies. A person who loves to read will definitely find a library, a bookstore, or books beautiful than other things, and the same goes for a car enthusiast who see beauty in cars or races.
It helps us by letting us appreciate the things that we currently have today and it helps us work with our own imagination. Just think of our scientists – their hobbies were their motivation to create something extraordinary and spectacular and we are all using their inventions for our own benefit.
