I said once that the best answer to the trap question "Do you believe in evolution?" is "I believe in evolution the same way I believe there is a city called Philadelphia." I've never been to Philadelphia; no, Mr. Ham, I wasn't there. But I've heard about Philadelphia, I've read about Philadelphia, I've seen pictures of Philadelphia, when driving in Baltimore I've seen road signs directing me to Philadelphia, and I've even known people who (claimed to have) lived in Philadelphia--all of which adds up to sufficient evidence for "I believe there is a city called Philadelphia" to be a reasonable statement.
Those who are devoted to proving in their own minds that Science Is Just Another Religion tend not to understand this distinction, of course.
