The act of being creative is essentially to take existing things and ideas and to create something new out of them. We write with words and we paint with paint. These are the typical things we think of as being creative, but there are many ways to be creative.
However, the things we create end up creating us too, because the act of creating them changes us. We are a different person after each act of creating through what we learn about ourselves and the world via the creative process.
Many people think of the thing they create as their baby. It is not a baby, it is a thing that exists because of you, but it is not a human being.
The human being in the creation process is the creator. If you want to use the Parent Child analogy then the creator is more like the Child, because the process of creating changes us and contributes to creating who we are.
