Pretty much. Most religions are happy to trumpet their acceptance of scientific findings, up until the point where it starts to seriously challenge their beliefs. Currently in vogue is the practice of finding vague overlaps between religious texts and, say, astrophysics. This is selective interpretation, post-diction, confirmation bias, and probably some other logical fallacies I'm forgetting. Like any good pattern-seeking species, we can find all sorts of "connections" when we look for them. Doesn't mean that they are valid, especially when we must ignore so much that is contrary to our current knowledge in order to find occasional similarities.
Strictly speaking, though, empirical tests cannot comment on the transempirical: that is, they can't say anything about the supernatural (i.e. God, the idea of a soul, etc.). Scientific studies can, however, support, refute, or call into question religious claims of supernatural forces affecting material reality. This includes a wide array of religious and/or paranormal claims, and is what, unfortunately, creates the societal divide between the two camps in many cases.
As to the specific stories mentioned in the opening post like the Arc, flood, and so forth, those are obvious myths. They are pursued as scientific facts only by fringe groups who take a much more literalist approach to all portions of the Bible, not just the New Testament.
