No Gods are known to exist, nor is the category of supernatural phenomenon gods fall into. So this is not a credible option to explain anything.If we go with natural theology and simply define God is as whatever the answer is to a set of metaphysical questions and if we accept the Principle of Sufficient Reason as a premise, then it's trivial to construct a logical proof of the existence of God.
1. The universe exists.
The universe and the order that it displays (laws of physics etc.) exist. That's seemingly self-evident to both common sense and to science.
2. For every x, if x exists, then a sufficient reason for x exists.
This is the Principle of Sufficient Reason, the idea that for any x, a reason exists at the very least for why that x is what it is and not something else. Science seemingly embraces it when it seeks explanations for things as varied as the existence and diversity of life on Earth, the origin of geological landforms or of the Solar System itself. Science isn't satisfied with being told 'That's just how things are'.
3. God is the universe's sufficient reason.
By definition, simply by describing how the word 'God' has often been used in natural theology.
Pick an option known to exist that can explain an effect.
