The dichotomy you attempt to set up - either God or no-God - is simplistic to the point of being infantile.
What are the other options?
As to what makes scientific explanations superior to Goddidit explanations - that speaks for itself - and I have repeated it many times.
And the problem with God doing it is what, exactly?
How is that worse than nothing did it? IOW, how is *It just happened* a better option than God doing it?
Propagandists don’t answer questions, mom. They merely throw turds in the well water.
That something happened by physical laws ( which I and many others think were designed by GOD) is useful. Assuming it happened by miraculous intervention is useless and inapplicable to anything else. I am sorry that you think that science is anti God. That attitude says a lot more about your limitations than it does about the limits of science.
