The Case for Theism

[Angrboda]

If you say there are either one or no cars in my neighbor's garage and I point out that maybe my neighbor has two cars in her garage, is that being disengenuous in your eyes?

It is if you yourself don't actually believe there are two cars. Why raise a possibility you yourself don't believe is true other than to be argumentative?

While I don't consider your analogy to a court case appropriate, as long as you brought it up, allow me to point out something. It is exceedingly common for a defense attorney to suggest alternative explanations for the facts in order to establish "reasonable doubt" as to the prosecution's story of how events came to pass. It is the prosecution's obligation (yours) to demonstrate that these alternatives are contradicted by the facts of the case. Any prosecutor who attempted to dismiss the introduction of alternative explanations by claiming that "the defense doesn't actually believe that is how things happened," asserting that it's "just a cheap legal trick," and not providing reasons for believing that that is not how things happened, such an attorney would soon find himself out of a job. Your objections make neither logical nor legal sense.
