Dear Fellow Creationists: As it turns out, this topic of the "firmament" is also of great interest to atheists. A popular anti-creationist made a 40-minute YouTube video critical of this little article. Seems we hit a nerve. Many atheists have claimed that the Bible teaches that the earth is surrounded by a solid domed sky. Instead, the Bible actually teaches that the firmament of Day Two is the crust of the earth, which thereby rebuts the widespread false allegation of a dome. When we first published this little article, that extra bonus was unexpected. Therefore we've also embedded and responded to Brett Palmer's video.
Real Science Radio, broadcast on Colorado's most-powerful radio station, aired a program discussing this topic. Please see the rest of this article on that page at rsr.org/firmament.
