Ok, for one, the bible is not true word for word. Science and the bible relate in no way. For one, the Old Testament is written in a much different time than the science we now know today. Noah's ark, is just a story I think to teach a lesson, where did the water come from, and where did it go? It is not possible in other words. Most stories are to teach a lesson.
Btw, the commandment is "Thou shalt not Kill." the ones listed on page 2 were the shortened form.
Also, as a side note, I'm a Catholic.
