This question has roots more deep than our reason can comprehend. Ultimately, it gets to the question of existence itself.
Many philoshophers and scientists have battled with that very same question mark:
How can it be that mathematics, being after all a product of human thought independent of experience, is so admirably adapted to the objects of reality?
If Mathematics is human creation, than it makes no sense that it can portrait so well all the things we see in the world, even those who couldn’t have possibly be created by humans. It is this magical link between the tangible algorithms and the mysteries of creation.
For the things of this world cannot be made known without a knowledge of mathematics.
If creation and the World isn’t man-made, and yet it can be expessed through mathematical equations, than in some ways math is the “translation” of the complexity of the world into comprehensive form to us. Not only a tool to comprehend the world, but also a language in which we are able to communicate this understanding to others. It is a way to register knowledge for generations to come.
Mathematics as an expression of the human mind reflects the active will, the contemplative reason, and the desire for aesthetic perfection. Its basic elements are logic and intuition, analysis and construction, generality and individuality.
Mathematics is in itself the puzzle and the solution, the enigma and the answer, the mystery and the revelation, the means and the end.
Logic and mathematics are nothing but specialised linguistic structures.
Language is nothing but a structured system of transmission of ideas. As we read this, it becomes clear that Math was both discovered and created. We’ve discovered the world (and still do), and needed to express the underlying truth we’ve come to know, Math was the structure we’ve created to communicate that discovery. However, all the laws of Math aren’t human made, but rather obey a higher order of intelligence, in which we keep trying to attain. Math isn’t done, because there is still much more to de discovered, and much more to be transmited.
