Is It a Creation of the Human Mind?

There is an age old debate about whether mathematics is discovered or invented. Is it out there in the world, or is it created by the human mind? I think i've made my position clear right? It's a creation of the human mind. It starts in the brain, and that's why you can be blind and still develop mathematics. However, we select our mathematics in part because it's useful to the external world. And of course, the foundations of our mathematics were selected to evolution because they were useful in many animal species.
