"God did it" isn't remotely chaotic and is a much more consistent answer than what the scientific method turns. One of the key parts of the scientific method is that scientists are constantly throwing out theories that are thought to be reasonable but eventually turn out to be inconsistent with the evidence; the process is quite muddled.
And you can't justify why you think consistency of the answer is the best indicator. It is still unlikely to give correct answers about the truly foundational stuff, the scientists just don't know.

You're implying that we don't care about the truth when deploying force against our own community. I put it to you that this is an area where the truth is of utmost importance. It has immediate implications on how people live! The only reason we don't make a habit of deploying scientists in the courtroom is that their methods are ineffective at working out the truth in general. They are only good at deducing a small handful of truths that are usually only important to engineers.
