As I read Nick’s comment about the Bible and unimpeachable source, I’m not sure if he isn’t saying that Asimov considered God an unimpeachable source.

I can’t determine it from the syntax.

I'm sorry you misunderstood what I thought I was stating clearly. Let me rephrase:

He Dr. Isaac Asimov also wrote a guide to the Bible, considering it the Bible evidence, no doubt, from an unimpeachable source.
