What a super opportunity this is to witness!
Of what? That the Biblical account of Noah is no more than a fairy tale, and that anyone who believes is an idiot? You can’t witness about something that you’re unsure of yourself, and many Christians, struggling to reconcile the first 11 Chapters of Genesis with the pervasive, persuasive religious message of Darwinism and The Theory (Applied Like Law) of Evolution, don’t accept Noah’s account as literally true themselves. Undoubtedly, the movie will do a great job of reinforcing this in their minds, and in the minds of many others.
