Well, do the churches you've been to make any claims on the Earth being flat, having oceans guarded by sea monsters, being ~10000 years old, once having experienced a global flood in those 10000 years, etc? I am not a christian, and am somewhat ignorant of this, but I believe those are all things mentioned in the Book of Genesis; however, I doubt that most modern religious leaders would assert that those things are literally true, given the wealth of evidence gathered by science that would point to an alternative model.
