there is more evidence to support flat-earth then one might see at first glance, especially in the bible
"And the sun stood still, and the moon stopped until the nation took vengeance on their enemies. Is this not written in the Book of Jashar? The sun stopped in the midst of heaven and did not hurry to set for about a whole day." - Joshua 10:13
if the earth is revolving around the sun then God would have made the earth stop, and we all know what that would do...
I'm not sure how that verse is related to flat-earth but as far as God stopping the sun and moon, or the earth, it seems to me that the creator of this universe can change the rules and do what he likes with the sun, moon, and earth. It's also possible that what happened is that nothing actually stopped bit the earth and sun and moon aligned in such away that it appeared as though the sun and moon stopped, for a brief time. We see extremely rare and unusual astrological events from time to time. As I said I am not an expert, perhaps someone more educated can shed some light on that verse for us. Thanks for commenting!
