The word "science" has been overloaded; it means both a method for obtaining new knowledge, and a secular authoritarian religion with the trappings of science. Know the difference.
The scientific method demands that we constantly question existing knowledge. Religious tenets, in general, can't hold up to being questioned.
This makes for a useful litmus test: If you are allowed to question something, it's science. If you are not allowed to question, you are looking at a religious belief.
