The "god" part becomes an unnecessarily complex explanation. I prefer simpler explanations when they fit the data just as well as the complex ones. It also reduces te risk when trying to broaden out to other lines of enquiry.

As johsny said It makes the god explanation redundant for the large topic of species of life. There's no need to waste time or energy "disproving" god. The whole concept of god is simply useless to understanding - and so is a waste of time or mental energy.

But the so called explanations referncing god are typically such bullshit anyway nothing testable, no evidence, just "god did some shit", "isn't god cool/powerful". So they never were actually useful to scientific reasoning. However much they may pretend otherwise religions are so much more aligned with laws and social structures and norms of behaviour than they are about advancing science.
