Genesis is the first book of the Bible. It details God's creation of the Earth and all the life on it. A literal understanding of this book is essential for Christians; I am also convinced that a correct understanding of the book is necessary to understand our planet and its history. After God finished creation, He is reported to have said, "It is good." I take this to mean that the Earth--and the Solar System--were created in a relative state of perfection, at least before the Fall of Man and, later, the Deluge event. What I have to say now will probably alienate half of my readers (both of them). I believe God made the Earth with an un-fractured crust (no tectonic plates) and no vulcanism or seismic activity; with an upright axis (no inclination) and a circular orbit; and, therefore, with a climate defined mostly by latitude. Man lived with all the animals and plants ever created, including the dinosaurs. Though it was a golden age in one sense, man's increasing wickedness and the direct involvement of fallen angels caused God to initiate the Cataclysm, which altered the face of the planet and nearly killed all living things.
Much of the rest of the Solar System was damaged at the same time. Mars and Venus were heavily damaged and nearly destroyed. Both were, I believe, habitable--and, indeed, were inhabited by us. Why would God create a planetary system so damaged and disrupted? What we see now is the result of our sin, our turning away from God. It's not what He made for us originally. Why would He?--Dan Moore
