I've heard all of this before, but it's still a copout. Dawkins calls it "smuggling god thru the back door."
This kind of thinking makes the bible pointless though.
One could make similar arguments about the ten commandments. For example, I've questioned Christians about their acceptance of capital punishment, which seems to go against "thou shall not kill," and their response is that they interpret it as "thou shall not murder.". Using the literal vs non literal interpretation of the bible makes the bible irrelevant, it's like a blank slate that anyone can manipulate to fit their needs. Much like Jim jones did.
There are parts of the bible that are intentionally non-literal (allegories). Even if the creation story isn't literal that doesn't mean the ten commandments aren't either(fallacy of composition). Even if that did make the bible pointless it doesn't mean believing the bible is the word of god and believing in evolution is a contradiction(fallacy of distraction).
