Every week there’s a new monster (MOTW) where all the evidence for outsiders disappears, or there’s the mythology where the government is covering it up.
I’m a huge skeptic in almost everything, but if I saw what she saw, I would clearly believe. That’s plenty of evidence for me, and I’m an actual scientist (well PhD engineer. I definitely did real science in school though)

There’s a fan theory (that became my headcanon as soon as I heard it) that the episodes we see are the minority of their cases that are actually supernatural. Most of their cases have mundane explanations so Scully is always skeptical because she’s usually right.
