I enjoy traveling, whether taking a trip to visit relatives for Christmas or a summertime vacation to witness the beauty of creation. However, any trip with my family (wife and five kids) requires lots of preparation in order to achieve success. Clothes must be packed, bills paid, lodging reserved, and the list goes on. These tasks must also be accomplished in the proper order. Trying to pack clothes after a trip begins is highly unadvisable. Likewise, when the solar system formed, certain events needed to take place before others in order to establish a life-friendly cosmic habitat.
