It's foolish for Dennett and Dawkins and others to attack religions on rational grounds, which isn't to say that they don't deserve it. Religious people are wrong to attempt to present rational arguments for god.

But religion, when it avoids literalism, speaks a different language than science, for it isn't focused on explaining how. It is focused on being, a question science doesn't address directly. It's arguable that the entire premise of religion is to get beyond biology -- in terms of biological appetites and biological limits. Science is being applied to the same goal.
