Mainstream Christianity was not biblical literalist anyway. Read what Augustine or Origen had to say about interpreting Genesis.
Some terribly ill-informed people have. Plus ca change. Sadly, the experience of "Christianity" of many Americans is either caricature or some kind of novel and vulgar fundamentalism they grew up around that sprouted on American soil in the last century or two. Add to that the black legends supplied by the Enlightenment and others and you have a perfect storm of malicious ignorance.

That depends on which religion, doesn't it. The categorical claim doesn't make any sense, because the general notion of "religion" doesn't entail anything that is inherently at odds with science. And if there is a normative sense of what is or isn't religion, then this is even more true, because normativity means there is a correct religion or most correct religion, and you can't be correct without being true.
Some religious traditions, however, do make claims that are wide open to scientific discreditation (like the "Lamanite hypothesis" of Mormonism).
The way I see this is that science cannot disprove any particular religion, but it can probably offer more compelling explanations for the state of the world than religion can offer. People haven't flocked away from religion because explanations for the state of the world aren't really what people want from religion. They want a sop for their anxieties. they want community, etc. I think believing in nonsense is a real shitty way to get these things, but I'm not most people.
