Pseudoscience
There is a difference, however, between pseudoscience and religion. Astrology is a pseudoscience, because it pretends to be based on facts, but is not. Religions make statements which are certainly not scientific, and are not meant to be. Insofar as a religion makes no factual claims, it is not open to refutation. When it does make factual claims it is vulnerable. A good example is the decision of the Catholic Church to defend the ancient ideas of the heavens (Ptolemy) against the (then) new ideas of Galileo and Copernicus.
