Most of what science touches and teaches is through perspective of the scientific method, which is circular in reasoning (as taught by all Professors that teach logic), but is pragmatic in providing a working model with data.
I said observations can be facts and yield certainty said so from the start.
If science moves away from the scientific method which is circular in reasoning and can never be conclusive in yielding certainty, that yes, it can make positive claims.
But right now observations while can do away with perspectives that are false, and often do with certainty, they often do away with things they think are false but haven't really done away with it, but all they have done is provided a different working model, that may or may not hold when investigating more details of the data or realizing different perspectives of the data, or dealing with edge cases.
