For centuries, beginning with Leonardo da Vinci, scientists accepted the account in Genesis chapters 1-11 as almost self-evident. As a result, they made few efforts to validate it. (Athanasius Kircher, who wrote a scholarly treatment of the voyage of Noah’s Ark, was one notable exception.) As a further result, those who doubted the Genesis account could easily persuade people not to believe it. But since 1960, many creation scientists have sought to show not only that those eleven chapters of Genesis happened as Moses wrote them down, but how they might have happened. Today, a careful scholar can read those chapters and imagine at least one, and often several, ways their story might have played out.
