You're probably taking this way out of context. Some parts -- few -- of the Bible are meant to be taken more figuratively than literally. Like Revelations. Not Genesis, or the Gospel. Anybody who has studied the Bible, or been taught the Bible, knows this. Just because some parts are to be taken more figuratively than literally doesn't mean any of it isn't true.
Ok, then, why should we believe the Bible's true? Any of it? Why should we believe Genesis, when science has alternative explanations based on facts? Why should we take anything on "faith" instead of relying on our own minds to find explanations?

I do not subordinate my life or judgment to the will of the majority/collective, and neither do you. Neither should you subordinate your life or judgment to the will of some "higher being," whether one exists or not.
