Several things.
First, an argument is only as good as its premises. I have yet to be presented with an argument for the existence of a god of which the premises aren't loaded with logical fallacies. I really don't understand how a person like William Lane Craig can be taken seriously by anyone.
Secondly, I don't see how such arguments matter at all. A philosophical argument by itself is not capable of showing the specific actual existence of anything without having actual empirical data to support it. Pure philosophy has its place, but distinguishing existence from non-existence of specific objects or entities is not one of them. Not without empirical data.
Since the OP of this thread is the broad question "does a god exist?" with a request to offer the evidence and arguments... how about YOU propose an argument to support your position that a god exists? I'll show you how it's fallacious, don't worry
Observing that there is suffering and injustice are things consistent with a universe not ruled by a loving god who cares and has the power to interfere.
I wouldn't really call it evidence as it could be that this guys has his reasons not to interfer and that somehow it's the moral thing to do. It could be that we don't see the big picture.
But it could also be that we live in the matrix.
As you say, we look for the
best explanation. The
best explanation is generally the one that needs the least assumptions,
even if it turns out to be wrong in light of new evidence.
Seeing as your entire proposed explanation is completely for 100% dependend on
faith based assumptions, it could not possibly be the best explanation. It's not even an explanation. Your entire story is a gigantic faith based assumption.
In science, the explanation also needs to be plausible. Anything is possible. Evidence for a specific thing makes the thing
plausible.
There is no evidence of gods.
And "god-dun-it" is not an explanation. In fact, it's a thing that requires it's own ginormous explanation. Your "explanation" needs an explanation. That can't be good.
