Good science is a very high bar. A theory must be proven universally true. That is why science is always a long way behind conjecture.
Name a single scientist fact that will not be proven at least partially untrue in the future. Not possible.
For example. You know that there is no such thing as gravity right? There is no force whereby one object attracts another. What we thought was gravity is a distortion of the fabric of space-time caused by mass.
Science is a very low bar. It describes the world in our current, and somewhat limited, understanding thereof.
