Science is not something to be believed in, it is a methodology that involves making and testing theories etc. People argue about it is and how it works and should work (philosophy of science is a significant field in itself) and it is not well defined, but what it is NOT is a body of facts.
Particular scientific theories may be believed in (or not believed in).
That said their samples sentences also include things such as "We’re assembling a crew for a heist" so maybe not take these things too seriously?
Some of the examples are references from the shows on Nebula. That one is likely from HAI Crime Spree. "Enter the Snack Zone" is from Jet Lag: The Game.
The font looks ok. This is an off putting sample sentence though. It sounds like a secular, pseudo-liturgical version of the Nicene creed.
