Science itself is just that, a shared set of beliefs as detailed by theories, the Scientific method itself a dogma and there are numerous common philosophies mingled together all rooted in materialism.
The latter, materialism, is why most people do not believe Science is a religion, because most religions over the years always had elements that at face value seemed supernatural and thus non-material. This misinterpretation is mostly because materialists recognize integrated symbols (from the cultures of the people in the religions) or allegories as literal when that is not the case.
And this is also why there is so much of a rift in politics concerning Science, because many people that support it do not realize that the knowledge it presents is not absolute and thus just as fallible as some of the seemingly ludicrous alternatives. Numerous theories are also heavily laced with other religious beliefs and many people do not even see the relationship.
Don't get me wrong, there are numerous aspects to Science that have been a huge help to innovation and progress, such as the requirements of reproducibility, but anyone that thinks that the Scientific method is they ONLY way to discover things needs to spend some time diving into the history of humanity's technological progress.
