Nope, lots of fluids that just flow over such a long period they appear solid.
What I said is true but not for glass. Pitch is a liquid even though it feels like a solid and shatters when smashed.
so then it does flow over time, just not on a scale where it matters to us.
The physical mechanism would be similar in glass flowing in this way, so I don’t think evidence of glass flowing like this should make us think of it as a liquid instead of an amorphous solid
Glass flows a higher temperatures where it does act like a liquid, you can study glass blowing for examples, however no, room temperature glass is not a liquid and does not flow, for any practical definition of what flowing is.
