Earth is flat in the Bible? Hmmm...I must’ve missed that, Where does the Bible say the earth is flat?
Taken together, the various Biblical descriptions of where we live pretty clearly describe a flat surface with a dome overhead keeping out a bunch of water, with lights affixed to the dome. That's what the plain meaning of the words describes. To get around that requires contortions about how "circle" really means "sphere" and "windows" are really "clouds" and all kinds of other interpretations of what it says in light of what we now know. Unfortunately, for some reason we're not allowed to make the same kind of interpretation in light of what we now know about the age of the earth and the history of life.
