Dr. Craig is a liar.

[The Reality Salesman01]

Except for when I'm being Poe, and demanding that the same requirements that others put forth they hold up to as well.

I tend to hold beliefs in varying degrees of certainty. I'm not married to any of them and they are all subject to change. But some things I'm more confident in. I wouldn't expect you to be able to prove every little thing you claim to be true...just the outrageous stuff that I see no evidence for.

I don't believe that we need to understand something in order to believe it. 

I do. I know that I'm vulnerable to believing things that are not true, and so I try to notice when I'm sliding down a slope of gullibility. And before I go forming a core belief to live my life by, I'm going to be applying quite a bit of scrutiny to it.

I think that the principle of causality is fairly foundational to science

I agree. I'm not sure if foundational is a word, but it should be! Are you saying that since the universe had a cause, then that cause must be God?

The only causal arguments I ever hear go something like this:

p1: All things that come into being had a cause.
p2: The universe came into being.
c:   Therefore the universe had a cause.

I'll grant you all of those things. But there is a detail that gets overlooked. All things that come into being have not only a cause, but they also have a prior existing form (example: ice/water/steam) And this is true whether or not you can explain it. It's observable and can be repeatedly demonstrated.

It is not true that all things that are caused "into being" have a cognitive artificer. That's a non-sequitor- (example: ice/water/steam).

So, the universe came into being, it was caused by something, and given our understanding of the way things work around here, the universe was probably some other (?) before it was a universe. There's not much else that can be said without pretending to know things that we don't know...
