There's a difference between religion and willful ignorance. If you want to believe or disbelieve something unprovable, fine - that can be defined as religion, or conjecture in science-speak. But to believe or disbelieve something in the face of observation, clear evidence, and fact - that is not religion.

Why is that not religion? Certainly there are religions that fit themselves entirely within the "believe something unprovable" niche, but there are a lot of religions that go much farther than that.
