Contribution

It emphasizes that mathematics, including π, is a human construct and not an inherent part of the physical universe.

Findings

Mathematics is created by humans.

The number π did not exist 100,000 years ago.

Mathematics relates to the physical world and human knowledge.

Abstract

In this article, I discuss the relationship of mathematics to the physical world, and to other spheres of human knowledge. In particular, I argue that Mathematics is created by human beings, and the number $\pi$ can not be said to have existed $100,000$ years ago, using the conventional meaning of the word `exist'.
