Mathamatics is in no way the same situation as religion.
While one could argue that maths is a creation of man, it is an example of logic, not a creation of belief like religion. In religion, you are expected to, on faith alone, assume things to be true. Example being that in christianity, you have to accept the Bible, in full, as truth. This is based entirely on faith.
With mathamatics, on the other hand, it is all based on logical extensions. There are not any jumps of faith...you develop the larger body of math as a whole by following logical conclusions and proofs from that which you already know.
Maths is then used to be able to accurately predict all manner of things, proving its accuracy. I'd be interested to see where it is maths does not work currectly.
The nearest comparison would be that people discovered the Law of Gravity. While gravity existed prior to Newton, the law that explained it did not. however, observations were made, eventually the law was formed, and is constantly being refined to become more accurate.
This also does show the main difference between maths/sciences and most, if not all religions. Where innaccuracies do exist in maths and sciences, or where things are not adequately explained, the idea is to change our beliefs on how things work to better reflect the real world. In contrast, in religion, the tendancy is to try to manipulate what is observed to be accurate with the assumptions initially made in religion. Maths/sciences are an attempt to explain how things work. Religion is a version of how things supposedly work that one then tries to prove using only scattered proof from the real world.
