The likelihood that aliens crash landed in Roswell (closer to Corona), New Mexico in 1947 is very slim. The odds that the wreckage was really a weather balloon, or some high tech spy device that failed, is much higher. But how interesting would the crash of a weather balloon be? Would you read a story or watch a movie about that? What if the wreckage was a spy device? Would that interest you?
Regardless of who was lying or who was mistaken, the story has life because it is unusual, it is full of conflict, it is mysterious, and we feel we can learn something new from it.
When you do something creative, what kind of life do you want that project to have?
