Perhaps if I give an example? Until about the mid-20th century, many (if not most) astronomers and cosmologists believed in a steady state model of the universe. However, it was then discovered that all observed galaxies show a red shift, indicating they are all moving away from us. This would not be predicted by a steady state model, and instead indicated an expanding universe consistent with the Big Bang model. Subsequently, other highly specific and empirically measurable predictions of the Big Bang were confirmed, and now pretty well every scientist rejects the Steady State model in favour of the Big Bang.
That is not the case for God. Even though there are scientists who are personally convinced one god or another exists, they will not usually claim that this has been established as a scientific fact.
Why is that? It seems to me that, by far, the most plausible explanation is that scientific evidence does not point conclusively to the existence of a god. Do you disagree?
