Problem
1. What would you say are the most important ingredients or conditions required for the emergence of life? Support your answer.
2. Are you more or less likely now, after what you have learned in this module, to believe that there is extraterrestrial life "out there somewhere?" Intelligent life? What is it that you learned that leads you to have that view?
3. Do you think we should try to contact alien civilizations? Do you think an intelligent alien civilization would want to communicate with us? Why or why not?
