One could choose to see the vastness of space, then assume there is no God, however this assumption is solely based on what the viewer really wants to be true along with a surface view of the surroundings. Perhaps, a deeper look might reveal a different picture.
I think that a deeper look reinforces the idea that ours is a godless universe. Here's the argument. Please excuse its length:
Suppose that either Case A or Case B is true, but not both. If A were true, then we might observe Situation 1 or 2 to be the case, but if B were correct, only situation 2 would be possible. We make an observation and find that situation 2 is the case.
An example would be that if there were an intelligent designer - call this Case A - the universe might have physical laws or not. An intelligent designer could will the planets to move as the whim struck it, sometimes faster, sometimes slower, sometimes in an ellipse, and sometimes in a triangle. Call that Situation 1. An intelligent designer could also create regular laws. That will be Situation 2.
But a godless universe - Case B - can only find itself in situation 2. It needs regular laws to keep the planets in their orbits, and those orbits will always be elliptical, and the motions of the orbiting bodies predictable.
Situation 2 is observed. Which is the case, Case A or Case B?
We can't say. But I'm going to assert that case B is slightly more likely to be the case than it was before we observed Situation 2. The reason becomes obvious as we add more and more examples where the situation is one of two possible were Case A the case, but only one of the two is possible in Case B.
Another example: In a universe with an intelligent designer (Case A), we might (Situation 1) or might not (Situation 2) be protected from what would be needless suffering if there a god present capable of preventing it.
But in a godless universe, Situation 2 is inevitable. That suffering will occur. Once again, we observe Situation 2 to be the case. Does that establish the veracity of either Case A or Case B? Once again, no, not by itself, although we will see that it also makes Case B a little likelier than it was before we observed Situation 2 to be the reality.
In a universe with an intelligent designer (Case A), that intelligent designer might (Situation 1) or might not (Situation 2) be evident to us the way that the sun is. In a godless universe (Case B), we wouldn't be able to find a god (Situation 2). Situation 2 is the reality once again.
In a universe with an intelligent designer (Case A), that intelligent designer might (Situation 1) or might not (Situation 2) create us with the will to do only good. It might (Situation 1) or might not (Situation 2) interfere in our affairs. In a godless universe, there would be no such interference. Once again, Situation 2 is what we observe.
The vast universe is yet another piece of similar evidence:
In a universe with an intelligent designer (Case A), the universe might (Situation 1) or might not (Situation 2) look custom designed for us. In a godless universe (Case B), we will discover that the universe does not look custom made for us (Situation 2). Yet again, Situation2 is the observation.
Keep adding more and more of these, each with Situation 2 being observed, and eventually, by consilience - the confluence of a multitude of independent occurrences that all point to the same conclusion, each of which alone is not necessarily convincing, but when considered collectively, is compelling - we get a clear picture that Case 2 is very likely the case. Ours is a godless universe, at least in the sense of the creator, ruler gods of Christianity and Islam. There is still a place for deistic gods, for example.
This is the same reasoning that allows the IRS to catch unsophisticated tax cheats. If a mistake in the taxes were innocent (Case A), it would be random, and sometimes hurt the tax payer (Situation 1), sometimes benefit him (Situation 2). With the unsophisticated cheat (Case B), the mistakes always go the same way: In the tax payers favor (Situation 2). It is the absence of situation 1 occurring over multiple instances where it might have that identifies which Case is likelier the case.
