Then why was the very notion of terraforming never even mentioned in the show? One would think that would be a major factor in finding a new planet to settle on.
Because the only directive Galactica and the fleet had following the Cylon attack was GET THE FUCK OUT OF HERE. There was no time to prepare for settling--let alone terraforming--another planet. Imagine the materials, resources, capital, and time that would be required for such an endeavor, none of which the Colonials had post-Exodus. They barely had enough food and water to take along, and were running out of both rather quickly.
