What is by definition unobservable? In fact, if it was right in front of your face, you could not see it. What is so powerful that it can stir an entire galaxy like I would use a spoon in a cup of coffee?

A black hole.

The recent reveal of the first "picture" of a supermassive black hole 53 million light years away is truly one of the greatest scientific efforts and breakthroughs in modern times. Yet despite all the obstacles, over a period of ten years and fifty million dollars later, we have this spectacular success and breakthrough.

So if science can achieve such a difficult task, why not the same for god?

According to almost all theistic claims, this god does interact with this known universe. It created it, it grants miracles, it sent it's son down here for 32 years, it has caused disasters, it listens to our prayers, and it punishes unbelievers. And just like black holes, it may not be directly observable, but it's effects on this galaxy are tangible.

Based on a comparison to M87, a god should actually be easier to identify and discover.
