Dawkins has indeed been successful with his biological research, but not undisputed. Compared to theoretical physics, evolution theory has not yet reached the crispness of notions it may achieve in the future.
His standing in philosophical and social sciences is much worse, and obviously he does not care at all. (The same applies to many church functionaries and state "philosophers", which is no excuse.) We had that discussion in other threads. With my idea that Dawkins is jealous I am of course not absolutely serious, but it makes sense that Cain kills God instead of Abel.
I once watched a TV interview with an Italian Jesuit priest who is also a physicist. Summary: official Catholic theology is quite mistaken about the characteristics of God and creation, since its authors (including the then Pope John Paul II) do not have the insight from thorough study of physics. To know just the results does not suffice for that insight.
Physicists with no religious affiliation often have the same strong feeling that their science tells them something about God.
There is also a musicians' God, typically professed by lovers of Bach's music. The evidence, however, is not quite as convincing to the heathen.
